Question

The figure below shows two white quarter circles inside a rectangle..

A rectangle having length 60 ft and width 30 ft has two white quarter circles inside it.The part between two quarter circular arcs is shaded. The radius of the quarter-circular arcs is 30 feet each.

The area of the shaded portion is approximately _____square feet. Round the solution to the nearest whole number. Use 3.14 for pi.

Answer 1

it means both circle have 1/4th part of area in the rectangle

Answer 2

area of 1/4th part of 1st circle=pi*r^2/4
area of 1/4th part of 2nt circle=pi*r^2/4
so area covered by circle =sum of both above area=2*pi*r^2/4=pi*r^2/2
area of shedded portion=area of rectangle-area of circlr
@irishchelsc got it???

Answer 3

would 1413 be the answer guys.?

Answer 4

no this is the area occupied by circle
subtract it from area of rectangle that is =60*30=1800

Answer 5

1800-1413...?

Answer 6

387...?

Answer 7

yeah gotcha
