Question

Find the area of a circle of radius 14 mm. [ Take pe r =22/7​

Answer 1

Answer: 615.75

Step-by-step explanation:

Answer 2

Answer:

616 mm²

Step-by-step explanation:

The formula for the area of a circle is:

$\boxed{\begin{array}{l}\underline{\textsf{Area of a circle}}\\\\A=\pi r^2\\\\\textsf{where:}\\\phantom{ww}\bullet\; \textsf{ A is the area.}\\ \phantom{ww}\bullet\;\textsf{ r is the radius.}\end{array}}$

In this case:

$r = 14\;\sf mm$

$\pi=\dfrac{22}{7}$

Substitute the given values into the formula for area and solve for A:

$A=\dfrac{22}{7} \times 14^2$

$A=\dfrac{22}{7} \times 196$

$A=\dfrac{22\times 196}{7}$

$A=\dfrac{4312}{7}$

$A=616\; \sf mm^2$

Therefore, the area of a circle with a radius of 14 mm is:

$\Large\boxed{\boxed{\textsf{Area}=616\; \sf mm^2}}$
