Answer:
Step-by-step explanation:
V = 1/3 pi r^2 h Multiply both sides by 3
3V = pi r^2 h Divide by pi * h
= r^2 Take the square root
= r
Answer:
12 miles
Step-by-step explanation:
30 miles÷2.5 hours
30 miles ÷2.5
2.5 hours ÷2.5
12 miles = 1 hour
12 miles per hour
16x^2=9
x^2=9/18
x=sqrt(9/16)
x=3/4,-3/4
so the root of the quadratic equation are 3/4 and -3/4
Answer:
769 cubic ft
Step-by-step explanation:
Its volume:
Find the volume of a cylinder of radius 7 ft and length 5 ft:
The basic formula for his volume is V = πr²h. In this case, the volume is:
V = 3.14(7 ft)²(5 ft) = 769 cubic feet of water.
