Square metres.
This diagram shows a target made
from four concentric circles (circles
with the same centre). The radius
of the inner circle is 2 cm. The
radius of the other circles increases
by 2 cm each time.
Calculate the area of each of the
rings numbered 1, 2 and 3. Give
your answers to a suitable degree
of accuracy.

a

step-by-step explanation:

the answer is a

b. 153 students do not participate in sports and seventy-five 12th graders were surveyed

1. x> -5

2. x< 8

step-by-step explanation:

1. 2x> -10

divide by 2 from both sides of equation.

2x/2> -10/2

simplify, to find the answer.

-10/2=-5

x> -5 is the correct answer.

2. 3x< 24

divide by 3 from both sides of equation.

3x/3< 24/3

simplify, to find the answer.

24/3=8

x< 8 is the correct answer.

i hope this you, and have a wonderful day!
