The area of a circle is: pi times radius squared
140.37 units squaredThe area of this circle is: 140.37 units2
Radius is the square root of (71/pi) = 4.8 feet rounded to the nearest tenth
The area of a circle with a radius of 10 cm would be 100 times pi, or, rounded to the nearest hundreth, 314.15 cm2.
A circle with a diameter of 11 inches has an area of 95.03 square inches.
The area of a circle (to the nearest hundredth) with a 5-unit radius is: 78.54 square units.
B.50.27
If you have the radius, then area = pi*r2 which you then round to the nearest hundredth. If you do not know the radius but do know the diameter or circumference, you can calculate the radius. Otherwise you need to measure it.
15.13 feet
The area of a circle is: pi times radius squared
It is: pi*15.42 = 745.06 square units

radius is 5cm. pi x r2 is 78.54, /3, *2 is 52.36cm2
The area of a circle to the nearest tenth if its radius is 4.5 is: 63.6 square units.
The radius, to the nearest hundreth, of a circle whose area is 719 square feet is 15.13.Another Answer:-When: pi*radius2 = 719 square feetThen: radius = square root of 719/pi => 15.13 feet rounded to the nearest 1/100
