Question

Area = _× diameter× diameter

Answer 1

Answer:

The area of a circle is the amount of space the circle covers. The formula for calculating the area of a circle is A = π_r_2 where pi (π) equals 3.14 and the radius (r) is half the diameter.

Answer 2

Answer:

π/4

Explanation:

Let r be the radius of the circle, then

Area = πr²

        = π(diameter/2)²                                      [∵diameter = 2r⇒ r = diameter/2]

        = π × diameter²/4

 

        = $\frac{\pi diameter^{2} }{4}$

        = $\frac{\pi}{4}$ × diameter²

        = $\frac{\pi}{4}$ × diameter × diameter

Hence,  Area = $\frac{\pi}{4}$ × diameter × diameter

Answer = π/4
