Answer:
SA = 1099 square inches.
Step-by-step explanation:
Just plug into the formula
SA = 2pir^2 + 2pi r h where pi = 3.14, r = 5 and h = 30
SA = 2 (3.14) (5^2) + 2 (3.14)(5)(30)
SA = 157 + 942
SA = 1099 square inches.

im sorry if its wrong
Step-by-step explanation:
Answer:
Volume of Cone =

Thus, Volume = 16.75 cubic feet
Step-by-step explanation:
Volume of a cone is given by the formula

Where r is the radius and
h is the height
Given radius r = 2 and
height is 2 times that.
So height is 2*2 = 4
Plugging these into the formula we get:
Volume of Cone =

Thus, Volume = 16.75 cubic feet
