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
Answer:
6
Step-by-step explanation:
We have to use Pythagoras' identity twice to find y
The square on the hypotenuse is equal to the sum of the squares on the other two sides.
In right triangle MUT to find TU
TU² + 3² = 6², that is
TU² + 9 = 36 ( subtract 9 from both sides )
TU = 27 ( take the square root of both sides )
TU = =
= 3
In right triangle NUT to find y
y² = 9² + (3 )² = 81 + 27 = 108 ( take the square root of both sides )
y = =
= 6
