First find the radius of the circle by dividing the circumference by 2*pi which works out as 3.501408748 units.
Area = pi*3.5014087482 = 38.51549623 or about 38.5 square units
The area of a circle with a 22-unit circumference is 38.515 square units.
Divide the circumference by (2 x pi) to get the radius. Then use the formula for the area of the circle.
Circumference of the circle is 22 units. Circumference of the circle is 2*3.14(pi)*r S0, 2*3.14*r=22 r= 22/6.28 units.
The circumference is about 22 units.
Using 3.14 as Pi the area of circle is: 0
r = ~3.5 units.
Circumference of a circle = 2*pi*radius or pi*diameter 7*pi = 21.99114849 units Therefore the circumference ot the circle is 22 units correct to the nearest unit.
A = 38.515 in2
To the nearest hundredth, what is the area of a circle with a circumference of 22 units = 38.52 units squared.
The circumference of a 7-inch circle is: 22 (21.98)
38.52 units2
Using 3.14 as Pi the area of circle is: 0
