Question

a cylinder that is shown and the height is 10 inches high and has a radius of 2 inches what is the surface area let pi. 3.14​

Answer 1

`\large\boxed{S.A.=48\pi\ in^2\approx150.72\ in^2}`

Explanation:

The formula of a Surface Area of a cylinder:

`S.A.=2\pi r(r+H)`

r - radius

H - height

We have r = 2in and H = 10in. Substitute:

`S.A.=2\pi(2)(2+10)=4\pi(12)=48\pi\qpprox(48)(3.14)=150.72`
