Question

What’s this answer to this problem

Answer 1

radius=13

Circumference=26pi

Area=169pi

Explanation:

The radius is half the diameter (SP or PR or PQ). The radius is 13

Area= pi(r)^2

r=radius

r=13

pi(13)^2=169pi

circumference=2pi(r)=(pi)d

r=radius

d=diameter

2(pi)13=26pi

Answer 2

Radius is 13 and Circumferences is 81.64

Explanation:

You divide 26 by two to get the radius and multiply 2 time pi times the radius or pi times diameter to get the circumference.
