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.
How do you figure out the area of shapes using Pi?
i think you do d x pi
Does pie equal exactly 3?
No it does not exactly equal 3. Pi (that's how you spell it in math terms) exactly equals 3.14159265*just a note Pi does not in fact equal exactly 3.14159265 it is an irrational number therefor has no exact value although its decimal places will continue infinitely :)
What is the formula using pi for the area of a circle?
area of a circle is equal to pi times the square of its radius.. A=(pi)r^2
How do you find the area of a figure using 3.14 as Pi?
Use the formula for the particular figure
Why can't you figure the area of a circle exactly?
Because the area of a circle is pi*radius2 but the exact value of pi has never been determined because it is an irrational number.
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.
How do you find the surface area if you have the circumference?
Figure the radius (r=C/2 pi) figure the area (A= pi x r squared). Note - the pi's don't cancel out.

How do you figure pi radius of a circle?
The area of any circle = pi*radius2
What is the area of a circle which has a radius equal to 1?
The area of a circle can be calculated using the formula pi*(radius^2). So in this case, the area of the circle will be pi*(1^2), which is equal to pi.

What is the area of a circle with a radius of 7 feet?
The area of a circle is equal to pi*r2, where pi is the radius. In this case, the area is equal to pi*(7 feet)2, which is about 154 square feet.
What is PI exactly equal to?
3.14159265 ............ then possibly to infinity It's never been worked out exactly.
What is the formula using pi for the area of a circle?
area of a circle is equal to pi times the square of its radius.. A=(pi)r^2
What the answer to the area of a circle?
The area of a circle = Pi*r2 where r is the radius and Pi is approximately equal to 3.14
Is there a right triangle equal to pi?
No, it is not. A triangle is a two-dimensional figure whereas pi is a dimension-less number.
