Math question 3 :P answer fast....last one btw

a sphere of radius 6cm just fits into a cylinder.
A: what is the height of the cylinder?
B: Find the volume of the sphere.
C: find the volume of the cylinder

A. The height should be 12 cm because it is equal to the diameter which is twice the radius
B. Volume of sphere= 4/3 x Pi x r^3
= 4/3 x 3.14 x 6^3
= 4/3 x 3.14 x 216
= 904.32 cm^3 or cubic centimeters

C. volume of cylinder = pi x r^2 x height
= 3.14 x 36 x12
=1356. 58 cm^3

A. 12 cm

B. 288pi cm^3

V = (4/3)(pi)(r^3)
= (4/3)(pi)(6^3)
= (4/3)(pi)(216)
= 288pi

C. 168pi cm^3

C = 2(pi)(r)
= 2(pi)(6)
= 12pi

A = L(W)
= 12(12pi)
= 144pi

V = 144pi+12pi+12pi = 168pi

12 cm height cyl = diam of sphere

4/3 Pi 6^3 cm ^3 from Vol sph = 4/3 Pi r^3

Pi 6^2 * 12 cm^3 = Pi r^2 h
