The area of a circle (to the nearest hundredth) with a 5-unit radius is: 78.54 square units.
B.50.27
15.13 feet
It is: pi*15.42 = 745.06 square units
153.86
radius is 5cm. pi x r2 is 78.54, /3, *2 is 52.36cm2

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
