Question

What is the area of the shaded region in the figure below?

Answer 1

tried pythagoras theorem to get other side of rectangle ?

Answer 2

one side of rect is 6 and radius of circle is 5, so u only need other side of rect to get the area of shaded region.....which u get by pythagoras theorem

Answer 3

oh ok so i do the pythagoras theorem 3^2+b^2=5^2
9+b=25
25-9=16 suqare root is 4

Answer 4

5^2=3^2+p^2
25-9=p^2
p=4
area of shaded region=area of circle - area of rectangel

Answer 5

yes, thats your other side, = 4
now can u find shaded area ?

Answer 6

how do i do that

Answer 7

shaded region is the area of circle - area of rect , could u see that ?

Answer 8

how do i get the area

Answer 9

area shaded reg=pie * (5)^2 - 6*4
=25pie-24

Answer 10

area of circle = pi * r^2

Answer 11

area of rect = length * breadth

Answer 12

oh ok so the answer should 25pie-24

Answer 13

yup

Answer 14

yous right
