Question

The lateral area of a cylinder is 94.2 cm². The height is 6 cm. What is the radius?

Answer 1

The lateral area of the cylinder is equal to the base circumference times the height h.
So:
$94.2=2 \pi r*h$
$94.2=2*3.14*r*6$
so that r=2.5 cm

Answer 2

Radius= $\frac{ A_{L} }{2πh} }$
So the answer will be 2.5 cm
