How big is a circle to be 150 Sq ft?

Answer 1

'How Big???? '

Do you mean , circumference, radius, or diamter.

For 150 sq.ft.

Then

A = 150 sq.ft. = pi r^(2)

Algebraically rearrange

r^(2) = 150 sq.ft. /pi ( 3.141592....)

r^(2) = 47.74648293 sq.ft.

r = sqrt( 47.74648293... sq.ft)

r = 6.909882989... ft. ~ 8.9 ft.

Hence

diameter = 2 x 6.909882989... = 13.81976596... ft. ~ 13.8 ft.

Circumference = pi X 13.81976596... = 43.41607527.... ft. = 43.4 ft.

Answer 2

If the area of the circle is 150 square feet then its radius is about 6.9 feet
