Question

How to find area of a circle when diameter is given?

Answer 1

${\huge{\mathfrak{\red{G}{iven}}}}$

Diameter = d

${\huge{\mathfrak{\red{T}{o\:find}}}}$

Area of the circle

${\huge{\mathfrak{\red{B}{rainliest\:answer}}}}$

Now, Diameter (d) = 2 * r

Therefore, r = d/2

Area of a circle = ∏ ${r^2}$

Area of a circle = ∏ ${{(d/2)}^{2}}$

Area of a circle = ∏ ${d^2/4}$

Answer 2

first half the diameter and as we know radius is half of the diameter and then with the help of radius we find the area of circle with the help of formula

$\pi r {}^{2}$
