Answer:
diameter = 12 cm
radius = 6cm
circumference = 12
cm ≈ 37.68 cm
area = 36 cm² ≈ 113.04 cm²
Step-by-step explanation:
r = radius
d = diameter
C = circumference
A = area
The diagram shows a circle with a diameter of 12 cm
<u>Diameter</u>
d = 12 cm
<u>Radius</u>
r = d/2
⇒ r = 12/2
⇒ r = 6 cm
<u>Circumference</u>
C = d
⇒ C = 12 cm
<u>Area</u>
A = r²
⇒ A = x 6²
⇒ A = 36 cm²
If you use = 3.14 then:
C = 37.68 cm
A = 113.04 cm²
Hello there!
6q + 9 ≤ 9
Start by subtracting 9 from both sides
6q + 9 - 9 ≤ 9 - 9
6q ≤ 0
Then divide both sides by 6
6q/6 ≤ 0/6
q ≤ 0
--------------
The second equation
6q + 9 ≥ -9
Start by subtracting 9 from both sides
6q + 9 - 9 ≥ -9 - 9
6q ≥ -18
Divide both sides by 6
6q/6 ≥ -18/6
q ≥ -3
Good luck with your studies!
