Radius is 30 inches.
The radius is 30 inches.
We apply the formula for the area of a circle to determine the radius of the circle: Area is equal to π * radius^2. Now that we know the area is 2826 square centimeters and that π is roughly 3.14, we can rewrite the formula to find the radius: 3.14 * radius^2 = 2826 Dividing 3.14 across both sides: radius^2 = 3.14 / 2826 radius^2 is around 900.63. To find the radius, take the square root of both sides: radius ≈ √900.63 radius approximately 30.04 centimeters

The area of a sector of a circle with radius 12 and arc length 10pi is: 188.5 square units.
the formula for the area of a circle is pi times r squared (sorry this website does not work today for presenting this better) so 2826 = pi times r squared so dividing through on both sides bi pi gives you: 2826 divided by pi = r squared so r is the square root of (2826/ pi) 2826/pi = 899.5437384 so r is the square root of 899.5437384 = 29.99239468 r = 29.99 (to 2 decimal places)
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.
Pi times the radius of the circle squared = area And diameter is simply the radius x 2, since the radius is half the length of the circle.
The formula for the area of a circle is pi x radius2. The radius is half the diameter, and the diameter of an inscribed circle is the same as the length of a side of the square.The formula for the area of a circle is pi x radius2.

By using the other information supplied about the circle to calculate either its radius (from which its area can be calculated) or its area (if the circle is similar to another with a given area and some ratio between the two circle is given):If the diameter is given: radius = diameter ÷ 2If the circumference is given: radius = circumference ÷ 2πIf the circle is similar to another circle which has a given area, and the length ratio is given; square the length ratio to get the area ratio and apply to the given area.
area of a circle = area of a rectangle(parallelogram) formed by the sectors of circle with pi as length and radius as bradth.
