Mathematics
1 answer:
antiseptic1488 [7]2 years ago
3 0

Answer:

Step-by-step explanation:

Big circle:

R = radius = diameter ÷2 = 42 ÷ 2 = 21 cm

Area of big circle= πR²

                            =\dfrac{22}{7}*21*21=22*3*21\\\\\\= 1386 \ cm^{2}

Small circle:

Diameter of small circle  = radius of big circle = 21 cm

r = 21/2 = 10.5 cm

Area of small circle = πr²

                                =\dfrac{22}{7}*10.5*10.5 = 22 * 1.5*10.5\\\\\\= 346 .5 \ cm^{2}

Area of shaded region = area of big circle - area of small circle

= 1386 - 346.5

= 1039.5 cm²
