Question

Can I have a detailed explanation, so I can do this on my own please? I will fan and medal!!

What is the exact area of a circle with a diameter of 19m?

Answer 1

we have given that diameter = 19 m
we know that radius = diameter/2

so that we get radius = 19/2

formula of the area of circle = pi*r^2
plug r = 19/2 in the above formula

so the area of circle = pi*(19/2)^2

=pi(361/4)

= 3.14*361/4

the area of circle =283.385 square meter.
