Sandra Franklin · Answer 1

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

Zaria Alexander · Answer 2

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