Find the circumference.
Use 3.14 for it.
r = 5 cm
C = [?] cm
C= Ttd

Answers

Answer:

C=2(3.14)×(5)

C=31.4cm

The circumference of circle is 31.4 cm

What is circumference of circle?

"It is the distance around the perimeter of a circle."

Formula for circumference of circle:

"C = 2 × π × r,

where r is the radius of the circle."

For given question,

We have been given the radius of a circle.

r = 5 cm

We need to find the circumference of circle.

Using the formula for circumference of circle,

⇒ C = 2 × π × r

We need to use π = 3.14

⇒ C = 2 × 3.14 × 5

⇒ C = 2 × 5 × 3.14                        ...............(since  a × (b × c) = (a × b) × c)

⇒ C = 10 × 3.14

⇒ C = 31.4 cm

This means, the circumference of circle having radius r = 5 cm

is C = 31.4 cm

Therefore, the circumference of circle is 31.4 cm

Answers

Answer:

Flashlight ;  = $2.99

Water bottle = $1.50

Toothbrush = $1.29

Compass = $3.29

Step-by-step explanation:

Sales tax = 7%

Item: _____ price

Flashlight ;  = $3.20

Water bottle = $1.61

Toothbrush = $1.38

Compass = $3.52

Total cost = price of item + sales tax

Sales tax = 7%

Total cost = (1 + 7%) * price of item

Total cost = (1 + 0.07) * price of item.

Total cost = 1.07* price

Flashlight = 1.07*1.29 = $3.20

Water bottle = 1.07*1.50 = $1.61

Toothbrush = 1.07*1.29 = $1.38

Compass = 1.07*3.29 = $3.52

Answers

Answer:

x > -2.5 (-2.5, infinity)

Step-by-step explanation:

Given the inequality expression

5.1(3 + 2.2x) > –14.25 – 6(1.7x + 4

Expand

15.3 + 11.22x > -14.25 - 10.2x - 24

15.3 + 11.22x > -38.25 - 10.2x

Collect the like erms

Which pair of equations below is a result of constructing the altitude, h, in traingle ABC?

Answers

Answer:

sinA = h/c; sinC = h/a

Step-by-step explanation:

Which pair of equations below is a result of constructing the altitude, h, in Triangle ABC?

sinA= h/c

sinC= h/a

sinA= h/c

sinB= b/c

sinA= b/c

sinC= b/a

Solution:

A triangle is a polygon with three sides and three angles. There are different types of triangles such as right angled, acute, obtuse and isosceles triangle.

In right angle triangle, one angle is 90°. From Pythagoras theorem, the square of the longest side (hypotenuse) is equal to the sum of the square of the two sides.

In right triangle, trigonometric identities are used to show the relationship between the sides of a triangle and the angles.

sinθ = opposite / hypotenuse, cosθ = adjacent / hypotenuse, tanθ = opposite / adjacent

Therefore in triangle ABC:

sinA = h/c;  sinC = h/a

Step-by-step explanation:

volume=15×5×5+8×4×5+8×4×5

=375+160+160

=695 m³

Answer:

695 m^3

Step-by-step explanation:

With this object, there are three rectangular prisms. The equation to find the volume of them is L*W*H.

So, with the small one in the front, the sides are 8, 4, and 5, so do:

8*4*5 ---> 160

Next, with long middle one, the sides are 5, 5, and 15, so do:

5*5*15 --->375

Then, with small one in the back, 8, 4, and 5 again, so do:

8*4*5 ---> 160

To finish it off, add them all together.

160 + 375 + 160 = 695 m^3

Answers

Answer:

The area of the circle is equal to [tex]9\pi[/tex].

Step-by-step explanation:

Given that,

The area of sector is, [tex]\dfrac{17}{2}\pi[/tex]

The central angle is [tex]\dfrac{17}{9}\pi[/tex]

We need to find the area of circle.

We know that,

[tex]\text{Area of sector}=\dfrac{\text{central angle}}{2\pi}\times \text{Area of circle}\\\\\text{Area of circle}=\dfrac{2\pi \times \text{Area of sector}}{\text{central angle}}\\\\=\dfrac{2\pi \times \dfrac{17\pi}{2}}{\dfrac{17\pi }{9}}\\\\=9\pi[/tex]

So, the area of the circle is equal to [tex]9\pi[/tex].

Find the missing angle measures. This is 8th grade math btw

Answers

Answer:

w is 146

x is 90

y is 34

z is 56

Answer:

w = 146 degrees

x = 90 degrees

y = 34 degrees

z = 56 degrees

Step-by-step explanation:

Right angles will always add up to 90 degrees.

Straight lines will always add up to 180 degrees.

Since x is a right angle, x = 90 degrees.

Since z + 34 = 90 degrees (a right angle):

90 - 34 = z

90 - 34 = 56 degrees

Since x + y + z = 180 degrees (a straight line), simply plug in the numbers we have found already:

90 + y + 56 = 180

y = 180 - 90 - 56

y = 34

Since w + 34 = 180 degrees (a straight line):

180 - 34 = w

180 - 34 = 146 degrees
