Question

What is the volume in cubic feet rounded to the
nearest whole foot of the figure?

Answer 1

Volume Con = pi x radius^2 x h/3

Volume Sphere = 4/3 x pi x radius^3

Explanation:

Volume of shape = Volume of Cone + 1/2 x Volume of Sphere

Volume of shape = pi x radius^2 x h/3 +1/2 (4/3 x pi x radius^3)

Volume = (3.14 x 39^2 x (81-39)/3) + 1/2(4/3 x 3.14 x 39^3)

Volume = (3.14 x 1521 x 14) + 1/2 (4/3 x 3.14 x 59319)

Volume = (66863.2) + (124174.4)

Volume = 191037.6

Volume = 191038 cubic ft
