Question

please get me solve this ​

Answer 1

Step-by-step explanation:

1) πR^2-πr^2

π(R^2-r^2)

3.14(49-12.25)

3.14×36.75

115.395cm^2

2)πr^2-l×b

3.14×14×14-7×3

615.44-21

594.44cm^2

3) these four sectors will make a whole circle so, therefore

area of rectangle - area of circle

l×b- πr^2

20×14-3.14×4

280-12.56

267.44cm^2

hope you have got the answers
