What is the volume of the sphere with a diameter of 18 centimeters? Round to the nearest
hundredth.
Answers
Answer:
3054.024cm^3
Step-by-step explanation:
Given data
Diameter= 18cm
Radius= 9cm
The expression for the volume of a sphere is given as
Volume = 4/3πr^3
Volume= 4/3*3.142*9^3
Volume= 4/3*3.142*729
Volume= 9162.072/3
Volume= 3054.024 cm^3
Hence the volume is 3054.024cm^3
A marble is picked at random. Without putting the first marble back, a second marble is picked at random. Find the probability that first marble picked is green and second marble picked is red. Write your result as a percentage.
Answers
Answer:
Probability = 1/5 = 20%
Step-by-step explanation:
Prob (1st marble green) = Green Marbles / Total Marbles = 3/6 = 1/2
Pr (2nd marble red), without replacement = Red Marbles / Left Total Marbles = 2/5
Prob (1st marble green, & 2nd marble red) = 1/2 x 2/5 = 1/5
Prob in percent = 1/5 x 100 = 20%

In order to simplify this, we're going to use a property that's called the Distributive Property:

Where a, b, and c can be variables, constants, or both (like 4c).
Now let's simplify our expression:
[tex]\longrightarrow\tt{2(2z+9)}[/tex]
Multiply 2 times 2z and 9:

Hence, we conclude that the answer is: [tex]\tt{4z+18}[/tex].

the cost of fencing a circular field at the rate of Rs 12. per metre is Rs 2640 . find the radius of the field
Answers
Radius = 35 m
Step-by-step explanation:Given:Cost of fencing circular field is Rs 2640 at rate of Rs 12 per metre.
To Find:What is the radius of the circular field ?
Solution:Let the radius of circular field be r metre.
Here , if we'll divide the total cost by per metre cost of fencing then we'll get circumference of the circular field.
★ Circumference = Total cost/Cost per metre ★➯ Circumference = 2640/12
➯ 220 m
As we know that , formula of circumference is
★ Circumference = 2πr ★
⟹ 220 = 2 × 22/7 × r⟹ 220 = 44/7 × r⟹ 220 × 7/44 = r⟹ 20 × 7/4 = r⟹ 5 × 7 = r⟹ 35 = rHence, the radius of circular field is 35 metre.
Answer:
Solution given:
total cost =Rs 2640
rate=Rs 12/metre
We have
circumference of circle =[tex] \frac{total cost}{rate} = \frac{2640}{12} [/tex]
2πr=220m
r=[tex] \frac{220}{2π} [/tex]=35.01
r=35m(approximately)
the radius of the field is 35m.
