Question

find the answer......................​

Answer 1

$\LARGE\underline{\underline{\sf Given:}}$

• ABCD is square of side = 7cm

• DPBA and DQBC are Quadrant of circle of radius = 7cm

$\LARGE\underline{\underline{\sf To\:Find:}}$

• Area of shaded region = ?

$\LARGE\underline{\underline{\sf Solution:}}$

$\large{\boxed{\sf Area\:of\:Circle=(side)^2 }}$

$\implies{\sf (7)^2}$

$\implies{\sf 49cm^2 }$

$\large{\boxed{\sf Area\:of\: Quadrant=\frac{1}{4}πr^2}}$

•°• Area of two quadrant :-

$\implies{\sf 2×\dfrac{1}{4}πr^2}$

$\implies{\sf 2×\dfrac{1}{4}×\dfrac{22}{7}×7×7 }$

$\implies{\sf 77cm^2 }$

Area of shaded region = Area of 2 Quadrant - Area of Circle

$\implies{\sf 77-49}$

$\implies{\sf 28cm^2 }$

$\LARGE\underline{\underline{\sf Answer:}}$

•°• Area of shaded region is 28cm²
