Answer:
38.4895
Step-by-step explanation:
area of circle = pi * r^2
3.142 * 7^2 = area of the whole circle
as we only have 1/4 of the circle we divide our area by 4
(3.142 *7^2) / 4 = 38.4895
basically you are finding a quarter of the area of the circle. So the formula is 1/4πr^2
so that's 3.142×7^2 and then divided by 4.
hope this helps
