Question

If the circumference of a circle measures 3 4 π cm, what is the area of the circle in terms of π? A) 9 8 π cm2 B) 3 8 π cm2 C) 3 64 π cm2 Eliminate D) 9 64 π cm2

Answer 1

It should be 289pi cm2, but I don't see that answer

Answer 2

I get area = 289 π cm²

the circumference and area formulae for a circle are

C = 2πr and A = πr² ( where r is the radius )

2πr = 34π ( divide both sides by 2π )

r = 17 cm

and A = π × 17² = 289π cm²
