37.5 km is equal to 15 cm
So the amount needed=area of circle times height
area formula=pi times radius^2
height=3/4
so
pi=aprox 3.14
radius=7
3.14 times 7^2
3.14 times 49
153.86
times 3/4
115.395 in^3
answer is 115.4 cubic inches
Answer:
7 cm
Step-by-step explanation:
An equilateral triangle has all sides equal.
To find the measure of the side, simply divide the perimeter by 3. This is because a triangle has 3 sides.
21 ÷ 3 = 7
12+.60+ 12.60
12.60*20%
12.60*.20= 2.52
Tip should be around $2.52
Hope this helped :)
