Answer 1

b

Answer 2

Thank you ^

Answer 3

Can I ask how you got it?

Answer 4

area of sq=lengh^2=8

Answer 5

we know the area of the square is 8
the formula to find the area of a circle is pi r^2
so in order to find r (radius of circle), we have to find the diameter
we find that by using pythagorean theroem and finding the line going diagonally through the square a.k.a the dimaeter of the circle

Answer 6

once you find that, half it to get the radius

Answer 7

half length od side =sqrt2...ok?

Answer 8

use pythogoras theorem to find radius

Answer 9

once you find r, put into the area of a circle formula
and ur left with 4pi

Answer 10

does that help?

Answer 11

so shaded region =4pi-8

Answer 12

yes u r right

Answer 13

well done uzma
