Answer:
V = 75 pi m^3
or approximately
V =235.5 m^3
Step-by-step explanation:
The volume of a cylinder is given by
V = pi r^2 h
where r is the radius and h is the height
V = pi * 5^2 *3
V = 75 pi m^3
If we use 3.14 as an approximation for pi
V =235.5 m^3
When you're finding equivalent fractions, the best thing to do is to multiply the numbers.
2/6 is also equal to 1/3
2/6 is equal to 4/12
2/6 is equal to 6/18
2/6 is equal to 8/24
Hope this helps :)
It took Andre and Lin 1.5 hours for them to meet.
Speed is the ratio of distance travelled to total time taken. Speed is given by:
Speed = distance/time
Let d₁ represent the distance covered by Andre at time t and d₂ represent the distance covered by Lin at time t.
Hence:
5 = d₁/t
d₁ = 5t
3 = d₂/t
d₂ = 3t
Andre and Lin are 12 miles apart, hence:
d₁ + d₂ = 12
5t + 3t = 12
8t = 12
t = 1.5 hours
It took Andre and Lin 1.5 hours for them to meet.
