The area of a circle is represented by the equation A = π r 2 , where r is the radius. The area is 64 π m 2 . What is the length of the diameter? 4 meters 4 meters 8 meters 8 meters 16 meters 16 meters 32 meters 32 meters

16 meters

Step-by-step explanation:

Area of a circle = πr²

Diameter of a circle = 2 x r

where r = radius

If area of the circle is given, the radius can be determined by finding the square root of the area

64 πm²  = πr²

r² = 64 πm²

r = √64

r = 8m

diameter = 8 x 2 = 16m

the reporter's right

step-by-step explanation:

1/4 = .25 / 25%

75

step-by-step explanation:

you do x-29=46 (the number of cantaloupes sold)

in order to find x, you have to find what minus 29 equals 46, meaning you'd have to add 29 to 46.

29+46=75

if you replace x with 75, the equation looks like:

75-29=46

x=75
