Answer:

formula is πr² ( pi x radius squared)

Step-by-step explanation:

the value of π is 3.142...

multiply this value with the squared radius of the circle and you'll get your answer.

For example:

we have a circle with diameter 5

so, π x 5² = 3.142 x 25 = 78.5

Answer:

7) C) PQR ≈ TSR

8) B) 3

9) D) 102 ft

10) D) 21

11) C) 45

Step-by-step explanation:

7) C) PQR ≈ TSR

8) 2 * 6 = 12

so 4x = 12

x = 3

24/20 = x/85

x = 24 * 85 / 20

x = 202 ft

10)

QT/35 = 24/40

QT/35 = 3/5

QT = 35 * 3 / 5

QT = 21

11)

ΔKLM ≈ΔXYZ

9/4 = 2.25

XY = 9 ---> given

YZ = 7 * 2.25 = 15.75

XZ = 9 * 2.25 = 20.25

Perimeter ΔXYZ = 9 + 15.75 + 20.25 = 45
