Step-by-step explanation:
Answer:
530.93
Step-by-step explanation:
area of a circle = πr²
where r = radius
here we are given the diameter
to convert to radius , we divide by 2
so radius = 26 / 2 = 13
so we have A = πr²
==> plug in r = 13
A = π13²
==> evaluate exponent
A = 169π
==> multiply 169 and π
A = 530.93 ( approximately )
