Question

find the area of shaded region
​

Answer 1

Step-by-step explanation:

their are 2 semicircles but with different diameters

so,infirst the area will be 1/4 of area of circle

➡️πr²/4

➡️ radius will be half of diameter so ,= 21 /2

➡️22/7*21/2*21/2 ÷4

.➡️after simplying we get

➡️693/4

now area of second semicircle

➡️πr²/4

➡️22/7*14*14÷4

➡️after simplying we get

➡️ 154

so total will be 154+693/4

➡️LCM = 4

➡️616+693÷4

➡️1309/4

➡️327.25 cm²
