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.
What is the length of an arc if we know the radius of curvature is 12 in. and the area of the sector created is 252 in2?
It is 42 inches.
What is the radius of a circle witha circumference of 42 inches?
Circumference = 42 inches => radius = 42/(2*pi) = 6.68 inches (approx)
What is the radius of a 42 inch circle?
21 inches.
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?
Well, let's imagine that circle as a happy little friend on our canvas. To find the square footage, we first need to find the radius by dividing the diameter by 2. So, with a 42-inch diameter, the radius would be 21 inches. Then we can use the formula for the area of a circle, which is π times the radius squared. Just remember, there are about 0.00595 square feet in one square inch, so you can use that to convert your final answer.
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.
What is the area of a circle that has a diameter of 42 yards?
A circle with a radius of 21 yards has an area of 1,385.44 square yards.
What is the area of a circle that has a circumference of 42 inches?
Using 3.14 as Pi the area of circle is: 0
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).
How many square inches in a eight inch circle?
area of a circle = pi times radius squared = 3.1415... x (half of diameter of 8 inches)2 = 3.1415... x 42 = 3.1415... x 16 = 50.26548... square inches
What is the radius of a circle with a circumference of 42 meters?
