Find the volume in terms of pi of a sphere

V = 4000/3 pi ft^3

Step-by-step explanation:

The surface area of a sphere is

SA = 4 pi r^2

400 pi = 4 pi r^2

Divide each side by pi

400 = 4 r^2

Divide by 4

400/4 = r^2

100 =r^2

Take the square root of each side

sqrt(100) = sqrt(r^2)

10 =r

Now we can find the volume of the sphere

V = 4/3 pi r^3

V = 4/3 pi (10)^3

V = 4/3 pi 1000

V = 4000/3 pi

you divide the cost ($15) by the quantity (6) to get your questions answer. the yo-yo costs $2.50. hope this : )!

step-by-step explanation:

42%

step-by-step explanation:

we know,

total people = 60

total males = 25

percentage of males

= 25/60 × 100

= 25/6 × 10

= 25/3 × 5

= 125 / 3

= 41.

rounding of = 42%
