What is the length of the radius of a circle whose area is 100π?
The formula for the area (A) of a circle is A = πr2. If the area is 100π then 100π = πr2 : 100 = r2 : r = √100 = 10. The radius is of length 10 units.
What is the area of circle with a 10 ft radius?
Area of a circle = pi*radius2 Area = 314.159 square feet to 3 decimal places.
What is the area of circle with a radius of 10 feet?
Area = pi R2 = 100 pi = 314.16 square feet (rounded)
What is the area of a sector whose central angle is ninety degrees and has a radius of ten inches?
Well a circle has 360 degrees so a sector of 90 degrees has an area equal to 90/360 (or 1/4) of a circle with the equivalent radius. The area of a circle is defined as PI*Radius^2 so the area of a 90 degree sector will be 1/4*PI*Radius^2. The area will be 1/4*3.14*10^2 or 78.5 in^2.
How many square inches in a 20 inch Dia. circle?
15.707963267948965 square inches. I think.* * * * *That is a very accurate but very wrong answer.The correct answer is 314.159 sq inches (to 3 dp).******Yes, the correct answer is 314.159. Here's why:The area of a circle can be found by multiplying pi (3.14159...) by the square of the radius. (The radius of a circle is 1/2 the diameter)This 20" circle has a radius of 10", so its area is 3.14*10"*10"=314.159
