Question

2 cm
A) 18.1 cm2
B) 12.6 cm?
C) 6.3 cm2
D) 24.7 cm

Answer 1

The answer is B 12.6cm

Answer 2

I'll assume you're looking for the circumference which is
`\pi r^2`

So plug the radius in to get the expression:
`\pi 2^2`
That equals
`4\pi` or in decimal form approximately 12.566 and answer choice b is closest so the answer is

B) 12.6 squared cm
