Question

Quizplus · Accepted Answer

The surface area of a cylinder is given by the formula $A = 2\pi r^2 + 2\pi rh$, where $A$ is the surface area, $r$ is the radius, and $h$ is the height. Given $A = 926$ square inches and $h = 7.35$ inches, we can solve for $r$. Rearranging the formula to solve for $r$ involves using the quadratic formula or iterative methods, but since the question is multiple choice, we can check which option works. Plugging the values back into the formula, option B, $r = 9.01$ inches, is the correct radius when calculated and rounded to the nearest hundredth.
