How do you find the area of a circle? Isn't it π and something?

Mathematics

Hi there!


You are partially correct on the π symbol, but there's more!


The formula for finding the area of a circle is:


A = π r².


A stands for area, π stands for pi, and r stands for radius. The ² is there because the radius is half as big as the diameter of a circle.


Hope this helps! :D


And remember, you can message me whenever you need to on anything you may need help with!

If the diameter is 12 inches, the radius is 6 inches, because the radius is half the diameter.

Given the formula

A=\pi r^2

we have

A=36\pi

When you fold the circle in half, the resulting figure has half the area.

So, you start with a circle with area 36\pi

You fold it once and you have a semicircle with area 18\pi

You fold it twice and you have a quarter circle with area 9\pi

How to find the volume of a quarter-sphere?
Ganezh [65]

As the word suggests, a quarter-sphere is a quarter of a sphere, and thus the volume of a quarter-sphere is a quarter of the volume of the sphere.

The volume of a sphere is computed as

\dfrac{4}{3} \pi r^3

So, the volume of a quarter-sphere is

\dfrac{1}{4}\cdot \dfrac{4}{3} \pi r^3 = \dfrac{1}{3} \pi r^3
