Answer:
The ratio of circumference to diameter is a constant
Step-by-step explanation:
The first line on the page tells you the relation: the ratio of the circumference to the diameter is about 3.14.
__
Another way to say this is that the circumference is about 3.14 times the diameter.
Answer:
216 cm^3
Step-by-step explanation:
I am assuming this is a right triangular prism
V = area of the base * height
We need to find the area of the triangular base
A triangle = 1/2 b*h
= 1/2 (12)4
= 24
Substituting this into the volume equation
V = 24 * 9
216 cm^3
Step-by-step explanation:
Arc length formula is
where x is radinas.
A semi circle has a radian measure of
The radius is half of the diameter, 12 so the radius is
So the arc length is
Area of semi circle is
where r is the radius.
