What's the circumference of a circle that has an area of 25*pi square inches?

31.42 ft

Step-by-step explanation:The formulae used for the area of a circle is

A = pi * (radius)^2

where r is the radius of the circle

We know that the area is 25 pi so substitune that into the formula

25pi = pi(r^2)

r^2 = 25

radius = sqrt 25

= 5 ft

si we ignore the negative value of the square root since he radius cannot be negative.

Next we look at the formula for the circumference of a circle

C = pi(d)

= pi *(2r)

= 2(5)(pi)

= 10pi

= 31.42 feet

-7/8

step-by-step explanation:

instead of subtracting you add the -6/8 and -1/8
