Radius and area work

9. b) 3.14 m²

10. d) 36.98 cm²

Step-by-step explanation:

9: Area of circle: πr²

one fourth of a circle, so its 1/4πr²

1/4*3.14*2²

1/4*3.14*4

3.14

10.

Diameter is 4.3 so the width of rectangle is 4.3

both circle has diameter of 4.3 so the length is 4.3*2 = 8.6

Area - L x W

4.3*8.6

= 36.98

x is greater than 5

step-by-step explanation:

2x+7 is greater than 17

    -7                           -7

2x is greater than 10

divide by 2 each side

x is greater than 5

if you need just tell me and i will come to the rescue.
