Answer 1

Answer:

Result: The area of a circle with radius 1 is 3.142

Formula:

r = 1 d = 2 C = 6.28

A = πr2 = π(d2)2 A = C24π π = 3.1415 A = area C = circumference or perimeter r = radius, d = diameter

Answer 2

Answer:

We know that area of Circle =

$\pi \: r {}^{2}$

Put value in this formula = 22/7 × (1)^2

= 22/7

= 3.14285714
