Answer:
18.85
Step-by-step explanation:
So the circumference of a circle = 2πr
if the diameter is 6, then the radius is 3.
so 2π(3)
= 6π
= 18.85 units of measurement
Answer:
67.5 degrees
Step-by-step explanation:
The first angle is 45 and the second angle is x and the third angle is x (the second and third are equal)
We know the 3 angles of a triangle add to 180 degrees
45+x+x = 180
Combine like terms
45+2x=180
Subtract 45 from each side
45-45 +2x = 180-45
2x= 135
Divide by 2
on each side
2x/2 =135/2
x = 67.5
Answer:
9cm x 5cm x 3cm = 135 = 67,5cm 2
