Jeanie wants to hang a circular mirror in a frame in her front hall. Determine the area of the largest mirror Jeanie can hang if the frame has a circumference of 56 inches.
1 answer:
Answer:
<h2>254.5 in^2</h2>
Step-by-step explanation:
Given that the circumference of the frame is 56in
we can proceed to obtain the radius of the frame
we know that
circumference= 2πr
56= 2*3.142*r
56= 6.284r
divide both sides by 6.284
r= 56/6.284
r=8.9
approximately radius is 9in
therefore the area of the mirror that is largest would be
Area= πr^2
Area= 3.142*9^2
Area= 3.142*81
Area= 254.5 in^2
The largest area is 254.5 in^2
