Question

How do you find an area of a circle? and how do you find the area of a cicle thats in a square

Answer 1

Answer:

1. area of a circle = π$r^{2}$

2. to find the area of a circle inside a square is the same thing. but if you're trying to find the area of a square WITH a circle inside, you just subtract the area of the circle from the square.

EX: If you have a square that has an area of 24cm and then you have a circle that has an area of 16 cm. To find the area of the square, you just subtract 16 from 25, which would look like 24 - 16 = x

Pi means 3.14, if you want an exact number, on your calculator press the pi button.

r means radius, which is half the diameter.

Diameter is the length of a circle.

$r^{2}$ just means you square the number. squaring the number basically just means multiply it by itself twice (ex: $4^{2}$ is the same as 4 x 4)

Answer 2

Answer:πr²

Step-by-step explanation: Question 1: or which is the same thing as (22/7)²

Question 2: Find the area of the square which you can get from length², then find the area of the circle and subtract the area of the circle from the area of the square
