Question

The formula for the lateral surface area of a cylinder is S=2πrhS=2πrh , where r is the radius of the bases and h is the height.

Answer 1

Answer:

Option b

Step-by-step explanation:

S=2πrh

r=S/2πh

Answer 2

Answer:

S / (2 * pi * h) =  r

Step-by-step explanation:

S = 2*pi * r * h

solve for r

Divide each side by 2* pi * h to isolate r

S / (2 * pi * h) = 2*pi * r * h/( 2 * pi * h)

S / (2 * pi * h) =  r
