The area of the quarter circle = 346.19 miles²

Step-by-step explanation:

If the perimeter of a quarter circle = 74.97 miles

r + r + 1/4 * 2pi*r = 74.97 miles

2r + 1/2r * pi = 74.97

Multiply left and right of the = sign by 2 gives...

2 * ( 2r + 1/2 * r * pi ) = 74.97 * 2

( 4r + 2/2* r * pi ) = 149.94

r * ( 4 + 3.14 ) = 149.94

r * ( 7.14 ) = 149.94

7.14 * r = 149.94

Divide left and right of the equal sign by 7.14

7.14 / 7.14 * r = 149.94 / 7.14

r = 149.94 / 7.14

r = 21 miles

Area full circle = r² * pi

21² * pi

441 * pi

We need to calculate a quarter part of the area of the full circle, so

1/4 * 441 * pi

110.25 * pi

110.25 * 3.14

= 346.185, which rounded to the hundreth gives.

The area of the quarter circle = 346.19 miles²

346.19 miles²

Step-by-step explanation:

Perimeter (P) of the quarter circle is the curve + both sides.

Perimeter of the curve

Perimeter of the sides

2 sides = 2r

Perimeter = curve + both sides

Find the Area

36/60

36/2=18

60/2=30

18/30

18/3=6

30/3=10

6/10

6/2=3

10/2=5

your final answer would be 3/5 of an
