Question

Find the area of a quadrant if the radius is 7cm.​

Answer 1

Answer :

• Area of quadrant is 38.5cm²

Given :

• Radius is 7cm

To find :

• Area of quadrant

Solution :

Given,

• Radius is 7cm

We know that

• Area of quadrant = ¼ × πr²

↬ Area of quadrant = ¼ × 22/7 × (7)²

↬ Area of quadrant = ¼ × 22/7 × 7 × 7

↬ Area of quadrant = 38.5cm²

Hence,

Area of quadrant is 38.5cm²

Answer 2

As per given in the question it is asked to find the area of a quadrant

and given data is only the radius =7cm

now the formula for area of quadrant

putting the values in the formula we get

$A=\frac{\pi r^{2} }{4} \\A=\frac{3.14\times7^{2} }{4} \\A=\frac{153.86}{4} \\A=38.465cm^{2}$

hence the area of a quadrant =$38.465cm^{2}$
