Question 365456: 1)The area of a sqaure is 83ft2. what is the length of the side to the nearest hundredth?
2)If the area of a circle is 72cm2, what is the radius to the nearest hundredth? Answer by amoresroy(361) (Show Source):
You can put this solution on YOUR website! 1) Area is 83 sq ft
Let x = length of side of square
x^2 = 83
x = 9.11 ft
2)Area of circle = 72 sq cm
Let r = radius of circle in cm
pi*r^2 = Area of circle
3.1416*r^2 = 72
r^2 = 72/3.1416
r = sq root of 22.918
r = 4.79 cm
