Question

Will give crown thingy if right Can you find the area and circumference of a circle given the radius or diameter?

explain why or why not please

~thank you

Answer 1

Therefore it is possible to find the circumference and area of a circle if we are given the radius or diameter of the circle.

Explanation:

i) to find the area of a circle or circumference the radius , r, is required.

ii) if we are given the diameter, d. then we have to find the radius, r, by dividing the diameter by 2, that is
`d = (r)/(2)`.

iii) area of the circle is given by A =
`\pi r^(2)`

iv) circumference of the circle is given by C =
`2\pi r`

Therefore it is possible to find the circumference and area of a circle if we are given the radius or diameter of the circle.
