Answer:
A=23512.32
Step-by-step explanation:
The equation for the area of a cylinder is A=2πrh+2πr^2
If we substitute the radius and height, the equation would be A=2π(60)(2.4)+2π(60)^2
π can be shortened to 3.14 so it's A=2(3.14)(60)(2.4)+2(3.14)(60)^2
We're left with 904.32+22608
So the answer is 23512.32
Answer: 1. 28 2. 25

Didn't know if you wanted the explanation or not, so sorry. But I can put an explanation if you need it.
Step-by-step explanation: In this problem, we're asked to state the domain and range for the following relation.
First of all, a relation is just a set of ordered pairs like you see in this problem. The domain is the set of all x-coordinates for those ordered pairs. So in this case the domain or D is {2, 5, -1, 0, -3}.
The range is the set of all y-coordinates for those ordered pairs. So in this case our range or R is {4, 3, -4, 9, 1}.
Presumably d meanst distance and t means time.
When t = 1, d = 2.5
When t = 3, d = 4
d = mt + b
2.5 = m + b [t = 1]
4.0 = 3m + b [t = 2]
1.5 = 2m [subtract]
m = .75 = slope
b = 1.75 = d-intercept
d = .75t + 1.75
d = 15/4 + 7/4 [t = 5]
d = 22/4 = 5.5 m from sensor
