Question

how do i find if the area is 1976 square inches, what are the radius, diameter, and circumference of the circle?

Answer 1

Hello,
The area of the circle=
πr^2
or A=πr^2
1976=πr^2
Divided π or 3.14 from both side
1976/3.14=πr^2/π
629.3≈r^2
Square root from both side to get
r≈25.1 inches
d=2r
d=2(25.1)
d≈50.2 inches
C=πd
C=50.2π or C≈157.628 inches. Hope it help!
