Question

156) If x= 2in X A) P= 6.28 in B) P= 10.5 in C) P= 12.57 in D) P= 18.34 in​

Answer 1

P = 6.28

Explanation:

To find the perimeter of a circle, you would use the formula 2πr.

The diameter = x and x = 2

The radius of a circle is half the diameter so r = 1.

Now we just substitute to get our answer:

2 ·
`\pi` · r = P

2 · 3.14 · 1 = P

6.28 · 1 = P

6.28 = P

P = 6.28
