How do you find the area of the circle if the diameter is 60m?

Area = pi * radius squared A = pi*r2 diameter/2 = radius 60 meters/2 = 30 meters so, Area = pi(30 m)2 = 2827 meters squared =================


What is the area of a pizza?

The area of a pizza depends on the size of said pizza. If there is a certain pizza you would like to find the area of, all you need to do is: 1. measure the diameter of the pizza 2. split the diameter in half to get the radius 3. square the radius and multiply it by pi(3.14). For example, if I have a pizza with a diameter of 10 inches I would split that in half to get a radius of 5 inches. Then I would do this: (3.14) x 52. Which would end up being 78.5 in2. Tada, now you know how to get the formula of a pizza!

How many inches in a large pizza?

47 pee pee meters. (different person) By inches you should mean square inches because you're talking about area. Now to find the area of a circle, you have to find out the radius of the circle. The radius is half of the diameter, and the diameter is a line that goes half way through the circle. So when you find the radius, multiply it by itself, then multiply it by pi (3.14). If you didn't learn about all of this yet, than there's no other way I could help.


What is the area of a circle with a diameter of 20 meters?

Oh, dude, you're hitting me with the math questions! Okay, so the area of a circle is π times the radius squared. Since the diameter is 20 meters, the radius is half of that, so 10 meters. Plug that into the formula, and you get an area of 100π square meters. So, like, grab a tape measure and start marking out that circle, or just trust me on the math, whatever floats your boat.
