What is the radius of a 60 inch diameter circle?
30 inches; the radius of a circle is 1/2 its diameter.
How is pi in relation to a circle?
Pi is related to the area and the circumference of the circle. The area is Pi multiplied by the radius of the circle squared and the circumference is Pi times the diameter of the circle. if you're wondering how it works, pi is the area of a circle with radius of 1 (unit), and the circumference of a circle with a radius of ½ (unit).
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
How do you find the area of a quarter circle?
You find the area of the entire circle (pi x radius^2), and then multiply it by 1/4 or 0.25.
What is the area of a circle radius equal to 1?
The area of a circle is pi times (radius squared) Thus if radius is one inch then area is (pi) times (1) times (1) = pi = 3.1416 inches squared
What is the area of a square inside a circle where the radius of the circle is 2 inches?
1/2 inch
What is the radius of a 2 inch circle?
1 inch
Why is the diameter of a circle with a radius of 1 inch?
It is because your 1 inch is one circle 1 inch one circle one of each get it.
If a circle has a radius of 1 inch what is the circle's diameter?
2 inches. the radius is half of the diameter
If a circle's area is 3.14 what is the value of its radius?
If a circle's area is 3.14 (Pi), its radius is: about 1.
What is the area of a circle that has a 25 inch diameter?
Calculate the radius, which is simply 1/2 the diameter. Then use the standard formula for the area of a circle. ________________________________________________________________ The circle area = (pi) x diameter / 4 = 3.14 x 25/4 = 19.625 Sq inch
Area of a circle with 2 inch diameter?
In a circle, Area = pi times radius squared: A = (pi)(r^2) Since the diameter equals 2 inches, the radius is one inch: A = (pi)(1^2) A = pi = 3.14 inches squared
What is the diameter of an 1 inch circle?
1" if it's a 1" diameter circle, 2" if it's a 1" radius circle.
How many square inches are in a 10 inch diameter circle?
The area of a circle = (pi)(radius squared); radius = 1/2 the diameter. Therefore, this circle has an area of (pi)(52) = 79 square inches, to the justified number of significant digits.
What is the circumference of a circle with the radius of 1 inch?
Multiply the radius by (2 x pi).
What if the radius of a circle is 1 inch What is the diameter?
2 inches
