What is the diameter of a circle that is equal to pi?

If you mean the diameter of a circle with area pi, then the diameter is 2. If you mean the diameter of a circle with circumference pi, then the diameter is 2. If you mean the diameter of a circle with diameter pi, then the diameter is pi. If you mean the diameter of a circle with radius pi, then the diameter is 2pi.

Radius of 5m what is the circumference?

If you mean a circle: the circumference is equal to diameter x pi, or 2 x pi x radius.If you mean a circle: the circumference is equal to diameter x pi, or 2 x pi x radius.If you mean a circle: the circumference is equal to diameter x pi, or 2 x pi x radius.If you mean a circle: the circumference is equal to diameter x pi, or 2 x pi x radius.

What does pi radius 2 mean?

That would depend if you mean 2 times the radius times pi (2*pi*r) or the more likely scenario pi times radius squared (pi*r2). 2*pi*r is the formula of the circumference of a 2d circle. Pi*r2 is the formula of the area of a 2d circle.

What is the area of a circle with the diameter of 2 cm?

The formula of finding the area of a circle is: pi(r)^2 or pi(d/2)^2 Cuz r = d/2 So when d = 2, r = 2/2 = 1 pi(1)^2 = pi(1) = pi = 3.14...

What is Surface area of a cylinder with 7in radius and 22in length?

The formula for the surface area (SA) of a cylinder is: SA = 2*pi * r^2 + 2*pi * r * h By plugging in the values given here, (r = 7, h = 22), you get: SA = 2*pi * 7^2 + 2*pi * 7 * 22 SA = 2*pi * 49 + 2*pi *154 SA = 98*pi + 308*pi SA =406*pi SA = 1,275.49 inches squared
