Find the area of a circle with a radius of 3

28.27

Step-by-step explanation: first multiply the radius by itself 3 times 3 = 9

then take 9 and multiply it by 3.14 which is 28.27

hope this helps mark me brainliest

Step-by-step explanation:

So to find the area of a circle, you have to use this formula:

A = 3.14r^2

So just plug everything in like this:

A = 3.14 * 3^2

Then solve

A = 3.14 * 9

Area is = 28.26 units^2

i dont know

step-by-step explanation:

+25 = x

step-by-step explanation:

here x is the hypotenuse of a right triangle whose legs are 7 and 24.   by the pythagorean theorem, 7² + 24² must equal x²:

x² = 49 + 576 = 625.   thus, x = +√625 = +25 = x
