Question

What is the volume of a hemisphere with a diameter of 8.6 ft, rounded to the nearest tenth of a cubic foot? \text{Volume of a Sphere:}

Answer 1

Volume=166.519 cubic foot

Answer 2

volume V = 166.519071 ft^3

Explanation:

radius r = 4.3 ft

base circumference C = 27.0176968 ft

volume V = 166.519071 ft^3

curved surface area A = 116.176096 ft^2

base surface area B = 58.0880482 ft^2

total surface area K = 174.264144 ft^2

In Terms of Pi π

base circumference C = 8.6 π ft

volume V = 53.0046667 π ft^3

curved surface area A = 36.98 π ft^2

base surface area B = 18.49 π ft^2

total surface area K = 55.47 π ft^2

Volume of a hemisphere:

V = (2/3)πr^3
