What is the radius of a 42 inch circle?
21 inches.
What is the area of a circle with a radius of 4 cm?
Area of a circle = pi x (radius)2So, if the radius is 4 cm, the area is pi x 42= 50.265 cm2
Area of a circle with a diameter of 8?
50.2656 square inches The formula to find the area of a circle is ∏r2. Where ∏ is the mathematical constant and r is the radius of the circle. So 3.14 x 42. = 50.27 square cm or yds, (whatever the diameter was in).
What is the radius of a circle with a circumference of 42 meters?
The radius of a circle with a circumference of 42 meters is about 6.685 meters.

How many square inches in a 8 diameter circle?
Area = pi*42 = 50.265 square inches to 3 decimal places
What is the area of a circle with a radius of 4 cm?
Area of a circle = pi x (radius)2So, if the radius is 4 cm, the area is pi x 42= 50.265 cm2
How many square feet in a 42 inch diameter circle?
The radius of the circle is 21 inches. The area of the circle is (pi) times (radius squared) = pi times 441 = 1,385.44+ square inches. 1 square foot = 144 square inches. The area of the circle is (1385.44+ square inches) divided by 144 = 9.621 square feet (rounded to 3 decimal places).
What is the radius of a circle if its circumference is 42?
The radius of a circle if its circumference is 42 is about 6.68
What is the area of a circle with a radius of 4?
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.
