The radius of a circle if its circumference is 42 is about 6.68
The area of a circle is pi times the square of the radius: A = πr2. For a circle of radius 4, this is π x 42 = π x 16 = 50.265 units squared.A circle with a radius of 4 units has an area of 50.27 square units.
A circle with a radius of 21 yards has an area of 1,385.44 square yards.
Area = pi*42 = 50.26548246 or about 50 square cm
A circle with a radius of 42 feet has a circumference of 263.89 feet.
Area of a circle = pi x (radius)2So, if the radius is 4 cm, the area is pi x 42= 50.265 cm2

The radius of a circle with a circumference of 42 meters is about 6.685 meters.
Area = pi*42 = 50.26548246 or about 50 square cm
A circle with a radius of 42 feet has a circumference of 263.89 feet.
Area = pi*422 = 5541.769 sq inches to 3 d.p.
PIE r squared 3.142 X 42 = 50.24
If the radius is 42 meters, then you already know the radius.
It is: pi*42 = 50.265 square feet to 3 dp
