Question

A flashlight shining onto a wall illuminates a circular area with A diameter of 9.5 feet. What is the approximate area of the wall that the flashlight illuminates

Answer 1

Do the following equation to find the area: 4.75 squared × 3.14

Answer 2

you need to find the radius first, which is 1/2 of the diameter. In this case, it is r=4.75. So, the area will be π(4.75)^2=
