A circle of area 49(pi) has a circumference of what

14(PI)

Using the equation A=(pi) r^2
49(pi) / (pi)=49
the square root of 49 is 7
so r (radius) = 7
to find circumfrence, we use the equation C= 2 (pi) r
C= 2 (pi) 7
the answer is 14 (pi)

Area of a circle is pi r^2. So in your problem, radius must be 7.
Circumference is pi d.
So if r = 7, d = 14, so circumference is 14pi

Answer = 14(pi)

area = pi r^2
49 pi= pi r^2
(cancell out pi on both sides)
r = sqr root of 49
= 7

circumference = 2 pi r
= 2 (pi) 7
= 14 (pi)

Area is pi x r x r = 49pi

=> r = 7

Circumference is 2 x pi x r = 2 x pi x 7 = 14pi

i dont think its possible to answer that but heres the formula for area... r(squared)x pi(3.14)
