Question

Please help with this problem!!! Asap thank u so much!!!

Answer 1

A.
volume of a sphere is 4/3*pi*r^3
4/3*3.14*1.6^3 = 17.1486 cm^3
because it is a half sphere, divide that by 2:
8.5743 cm^3

b.
volume of a cylinder is base area (pi * r^2) multiplied by the height
The cylinder shares a radius with the half sphere, so this gives us:
3.14*1.6^2*6.2 = 49.8381 cm^3

c.
this is simply the combined volume
8.5743 + 49.8381 = 58.4124 cm^3
