Question

geometry the lateral area of a right cylinder can be found by multiplying twice π by the radius times the height. if a right cylinder has radius r and height h, write an expression that represents the lateral area.

a) πrh

b) πr²h

c) 2πrh

d) 1/2πrh

Explanation:

Step1: Identify the formula - given

The problem states that the lateral area of a right - cylinder is found by multiplying twice $\pi$ by the radius times the height.

Step2: Write the formula

If the radius is $r$ and the height is $h$, then the lateral area $A$ is given by $A = 2\pi r h$.

Answer:

C. $2\pi rh$
