Because is is a semicircle you do the same thing as you did with the rectangle but then divide by 2 or you can follow this formula
A=pi·r·r. (Area=3.14×radius×radius)
A=pi·r2. (Area=3.14×radius squared)

It’s a semicircle, so it would be 1/2 pi r^2.

Answer:

x = 6 cm

Step-by-step explanation:

Given ratio of sides of similar figures = a : b , then

ratio of areas = a² : b²

Here ratio of areas = 5 : 45 = 1 : 9 , so

ratio of sides = \sqrt{1} : \sqrt{9} = 1 : 3

Thus side of B is 3 times side of A

x = 3 × 2 = 6 cm

Answer:

9) x = 89°

10) x = 118°

11) x = 145°

12) x = 40°

Step-by-step explanation:

9) 180-91 = 89

10) x = 118° because it is alternate interior to 118

11) x-30 = 115,     x = 145

12) 4x-15 = 145,    4x = 160,   x = 40
