Question

who want a M-E-D-A-L

Answer 1

Surface area:


pi x r^2 + pi x d x h

Answer 2

volume:

pi x r^2 x h

Answer 3

Alright

Answer 4

3.14 * 3.5^2 + 3.14

Answer 5

3.14 * 3.5^2 = 38.47

Answer 6

38.47 + 2.14 = 40.61

Answer 7

surface area of a cylinder..

"

To find the surface area of a cylinder add the surface area of each end plus the surface area of the side. Each end is a circle so the surface area of each end is π * r2, where r is the radius of the end. There are two ends so their combinded surface area is 2 π * r2. The surface area of the side is the circumference times the height or 2 π * r * h, where r is the radius and h is the height of the side.

The entire formula for the surface area of a cylinder is 2 π r2 + 2 π r h "

The surface area is hard to calculate, so, lets do volume first.

Answer 8

ok

Answer 9

Sorry if im just like "ok", my brain is kid of fried so im just trying to hurry up and finish thats why.

Answer 10

*kind

Answer 11

It is ok, anyway,,


pi × r^ 2 × h


3.14 x 3.5^2 (12.25) x 14

Answer 12

which is 538.51
