how do you find the perimeter of a half circle

Answers

Answer 1

Answer:

The perimeter of a semicircle is the sum of the half of the circumference of the circle and diameter. As the perimeter of a circle is 2πr or πd. So, the perimeter of a semicircle is 1/2 (πd) + d or πr + 2r, where r is the radius.

Step-by-step explanation: .

Answer 2

Answer:

πr

Step-by-step explanation:

We know the perimeter of the circle is 2πr , half the perimeter will be equal to ,

=> 2πr/2

=> πr

Hence the required answer is πr .

Find the Volume (look at the picture)

Answers

Answer:

V ≈ 263.9 units³

Step-by-step explanation:

The volume (V) of a cone is calculated as

V = [tex]\frac{1}{3}[/tex] πr²h ( r is the radius and h the height )

Here r = 6 and h = 7 , then

V = [tex]\frac{1}{3}[/tex] π × 6² × 7

   = [tex]\frac{1}{3}[/tex]π × 36 × 7

   = [tex]\frac{1}{3}[/tex]π × 252

   = 84 π

   ≈ 263.9 units³ ( to 1 dec. place )

Which side lengths form a right triangle? Choose all that apply. 5, the square root of 8, 33 or 8,15,17 or the square root of 2, the square root of 2, 2

Answers

Answer:

17² = 15² + 8²

2² = (√2)² + (√2)²

Step-by-step explanation:

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. Hence:

33² ≠ (√8)² + 5² (not right triangle)

17² = 15² + 8² (right triangle)

2² = (√2)² + (√2)² (right triangle)

A parking space shaped like a parallelogram has a base of 19 feet and a height is 9 feet. A car parked in the space is 14 feet long and 6 feet wide. How much of the parking space is not covered by the car? The area of the parking space not covered by the car is

Answers

Answer:

87 feet^2

Step-by-step explanation:

area of the parking space not covered by the car = area of parking space - area covered by the car

area of parking space = area of a parallelogram = base x height = 19 x 9 = 171 feet²

Area of car = area of a rectangle = length x width 14 x 6 = 84 feet²

area of the parking space not covered by the car = 171 feet² - 84 feet² = 87 feet^2

The inequality that models the story is h < 16.

Step-by-step explanation:

The information provided states that Eduardo ONLY wants 16 hot dogs at most which means he doesn't want to cook anymore hot dogs than 16 of them. The line below the symbol means that it could also equal to that number which is what Eduardo also wants. Now that we know the inequality, we also need to graph it. All you need to do is plot the endpoint at 16 with an arrow pointing to the left. It also requires a closed circle because it doesn't mean just less than, don't forget, it means less than OR equal to. A closed circle just means to shade the dot by the way.

Answer: h < 16

Step-by-step explanation:

h (the number of hotdogs) has to be less or equal to 16

for the line do a closed circle on 16, and have the arrow go left

a. f(x)=2(3)^(x-2)+2


b. f(x)=1/2(4)^(x+1)

Answers

Answer:

[tex]f(x) = 2[\frac{3^x}{9}] + 2[/tex]

[tex]f(x) = 8(4)^x[/tex]

Step-by-step explanation:

Given

[tex]f(x) = 2(3)^{x-2} + 2[/tex]

[tex]f(x) = \frac{1}{2}(4)^{x+2}[/tex]

Required

Remove the h component

In a function, the h component is highlighted as:

[tex]f(x) = a^{x+h}[/tex]

So, we have:

[tex]f(x) = 2(3)^{x-2} + 2[/tex]

Split the exponents using the following law of indices:

[tex]a^m/a^n = a^{m-n}[/tex]

[tex]f(x) = 2*\frac{3^x}{3^2} + 2[/tex]

[tex]f(x) = 2*\frac{3^x}{9} + 2[/tex]

[tex]f(x) = 2[\frac{3^x}{9}] + 2[/tex]

The h component has been removed

[tex]f(x) = \frac{1}{2}(4)^{x+2}[/tex]

Split the exponent using the following law of indices

[tex]a^{m+n} =a^m * a^n[/tex]

So, we have:

[tex]f(x) = \frac{1}{2}(4)^x * 4^2[/tex]

Express 4^2 as 16

[tex]f(x) = \frac{1}{2}(4)^x * 16[/tex]

Divide 16 by 2

[tex]f(x) = 8(4)^x[/tex]
