Question

What is the surface area of the solid?
I'm giving medals.

Answer 1

You can break the image into 2 pieces a cylinder and a cone.

Answer 2

Using the surface area formula for a Cylinder and the surface area formula for a Cone you can add them up and find the surface area of your shape.

Answer 3

I need a formula.

Answer 5

Surface area of a Cylinder:\[A = 2 \pi r h+2 \pi r^2\]
Surface area of a Cone:\[A = \pi r s+\pi r^2\]

Answer 6

Where,
r = radius
h = height
s = side
PI = 3.14

Answer 7

We only need to use\[\Large \pi rs\] as well since the base of the cone is attached to the top of the cynlinder

Answer 8

\[A = 2 \pi r h+ \pi r^2 \] Will be the surface area in this question since one of the circles is attached to the base of the cone,

Answer 9

I got A.

Answer 10

it was c.
