please solve all of them

a. To the nearest hundredth the surface area of a sphere with a radius of 1.6 in. is __?__ in2.

b. To the nearest hundredth the base length of a square based pyramid whose volume is 26.784 m3 and height is 6.2 m is _?__m.

c. To the nearest tenth the height of a cone whose volume is 171.3 m3 and radius is 4.8 m is _?__m.

d. The volume of a cylinder with a height of 4 in. and a radius of 1.5 in. is __?__ in3. Round answer to the nearest tenth.

e. To the nearest tenth the height of a square based pyramid whose volume is 113.32 m3 and base length is 6.4 m is _?__m.

a) surface area of sphere = 4?(radius)2

= 4?(1.6)2

= 32.15

C) volume of cone = 1/3*?(radius)2*(height)

171.3 = 1/3*?(4.8)2*(height)

171.3 = 24.11*(height)

height = 7.1

d) volume of cylinder = ?(radius)2*(height)

= ?(1.5)2*(4)

= 28.26
