Question

Estimate the area of the circle using 22/7

Answer 1

Answer: $A_{circle}=616cm^2$

Step-by-step explanation:

You can observe in the figure that the value of the diameter of the circle is

$d=28cm$

Then, since you know the diameter , you can use this formula for calculate the area of the circle:

$A_{circle}=\frac{\pi d^2}{4}$

Where "d" is the diameter.

Then, substituting  $d=28cm$ and  $\pi =\frac{22}{7}$ into the formula, you can estimate the area of the circle. This is:

$A_{circle}=\frac{(\frac{22}{7})(28cm)^2}{4}$

$A_{circle}=616cm^2$
