Question

Help me please its for a test​

Answer 1

Answer:

15(radius) x 3.14 (pi)x 2(just always here when finding circumference) = 94.2

C is your answer. If we do part of the formula, 15 x 2 = 30, now we just need to multiply by pi. and 30π would be your answer.

Step-by-step explanation:

15 seems to be your radius, so lets just use the circumference formula!

C would most likely be your answer, it is partially done. 15 x 2 = 30, but now we multiply by pi and it says so in answer c.

Answer 2

Answer:
