To find the area of a circle based on its radius, multiply its radius squared by pi. Don't forget to square the radius before multiplying by pi, based on rules of BODMAS where you find powers of numbers before you multiply them.In this instance, (4.4 x 4.4) = 19.36. Multiplying this by pi gives us, accurate to two decimal places, 60.82. Don't forget to include the appropriate measurement. If the original measurement of the radius of the circle was in centimetres, then the area should be expressed in square centimetres. If the original measurement of the radius was in inches, then the area should be expressed in square inches.

You will get pi since area of a circle equals pi* times radius squared....by Mona Martinez

When you draw a circle in math, and you draw a triangle inside of it, 2 of the lines should be the radius of the circle, and the third (bottom) line that is not the radius is the chord.

To find the radius of a circle when given the circumference, you should start with the formula for circumference, which is this: circumference = 2*pi*radius To solve for the radius, you would the have to divide the circumference by 2*pi leaving you with a formula like this: radius = circumference/(2*pi) pi≈3.14159

Circumference = 2 x π x radius ⇒ radius = circumference ÷ (2 x π) So divide the circumference by 2 x π ~= 2 x 3.14 = 6.28 ⇒ radius = 22 inches ÷ 6.28 ~= 3.5 inches. As an approximation to π (the ratio between a circle's circumference and its diameter), the value 22/7 is sometimes used (to 2 decimal places 22/7 = 3.14 & π = 3.14). The circumference given as 22 inches suggests this approximation should be used: 22 ÷ (2 x 22/7) = 22 x 7/22 ÷ 2 = 7 ÷ 2 = 3.5
