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.
The area of a circle with a 22-unit circumference is 38.515 square units.
Radius = 22/2pi m
Using 3.14 as Pi the area of circle is: 0
A circle with a radius of 22 inches has a circumference of 138.23 inches.
r = ~3.5 units.
Divide the circumference by (2 x pi) to get the radius. Then use the formula for the area of the circle.
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.
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 radius is 3.5
The area of a circle with a 22-unit circumference is 38.515 square units.
Radius = 22/2pi m
Using 3.14 as Pi the area of circle is: 0
The circumference is about 22 units.
22/3.1416=diameter /2
A circle with a radius of 22 inches has a circumference of 138.23 inches.
as circumference of a circle = 2*∏*r where ∏=22/7 & r= radius so 168 = 2*22/7*r r = 26.72
