Question

Find the volume of a sphere with a radius of 14.5 cm

Answer 1

Answer:12763.6 cm^3

Explanation:

radius=r=14.5 cm

π=3.14

Volume of sphere=4/3 x π x r x r x r

Volume of sphere=4/3 x 3.14 x 14.5 x 14.5 x 14.5

Volume of sphere=(4x3.14x14.5x14.5x14.5) ➗ 3

Volume of sphere=38290.73 ➗ 3

Volume of sphere=12763.6

Answer 2

Therefore the volume of a sphere with a radius of 14.5cm is equal to 12,763.5cm^3 rounded to the nearest tenth.

Explanation:

The formula to the volume of a sphere is 4(3.14)(r^3/3)

Our radius is 14.5 so we can plug it into the formula.

4(3.14)(14.5^3/3)

4(3.14)(3048.625/3)

4(3.14)(1016.2)

12.56 x 1016.2 = 12763.472
