What is the exact area of a circle with a radius of 12 feet?
The area of a circle is equal to pi times the radius squared. A 12 foot radius circle would have an area of exactly 144 pi square feet.
What is the exact area of the circle with the given radius or diameter r 11.64 m?

Formula for exact area of a circle?
pi x square of radius
What is the exact area of a circle whos diameter is 6 cm?
There is no way to find the exact area of a circle. The formula for the area is Pi times the radius squared. But Pi is an irrational number -- that is, no matter how many numbers you write it out to, you could always write it further. Since there is no exact value of Pi there can be no exact value of the area based on the diameter. The radius is half that of a diameter. Therefore, if you know the diameter you know the radius. In this case the radius is 3cm and the area of the circle = pi * 32 So the answer is roughly
What is the exact area of a circle with a radius of 19 m?
168.56 square inches
What is the exact area of a circle with a radius of 18 feet?
The area is exactly (324 pi) square feet.
What is the exact area of a circle with a radius?
9.2 i think The formula is pi*r^2
If The exact area of a circle is 81pi square inches what are the radius and diameter of the circle explain?
The radius is 9 inches because area of circle is pi*9 squared = 81pi square inches and the diameter is twice the radius which is 2*9 = 18 inches
What is the exact area of a circle having a radius 6 inches?
area = π × tradius² → area = π × 6² = 36π.
What is the area and radius of a circle if it 14cm?
If what is 14cm? The diameter? The circumference?d = diameter, r = radius, C = circumference, A = area, pi = approx. 3.14If d = 14cm, then r = 7cm.A = (pi)r2 = (pi)(7)2 = (3.14)(49) = 153.86 = about 154cm2.If C = 14cm, use the formula C = 2(pi)r:14 = 2(pi)rr = 14/(2pi) = 14/6.28 = about 2.229 = about 2.23cm.Then A = (pi)r2 = (3.14)(2.229)2 = 3.14(4.970) = about 15.6 cm2.
What is the area of a circle with a 13 inch radius?
530.9291585 squared inches to be exact. * * * * * To be exact? Since when has it been possible to express an exact multiple of pi?
