Step-by-step explanation:
Hello There
The volume of a cylinder can be found using this formula

where r = radius and h = height
The cylinder shown has a radius of 8 inches and a height of 8 inches
Knowing this information we plug it in into the formula

Finally we round to the nearest tenth and get that the volume of the cylinder is 1607.7 in ^3
Answer:
t = 28 minutes
Step-by-step explanation:
Last Saturday, Camila practiced her dance routines for her upcoming competition. She spent some time practicing her tap routine, and then she spent 17 minutes practicing her hip-hop routine. In all, she practiced for 45 minutes. Let t be the number of minutes that Camila practiced her tap routine. Write and solve an equation to find t.
45 minutes = Number of minutes for hip-hop routine + Number of minutes for tap dance
The equation is given as
45 = 17 + t
Solving for t
t = 45 - 17
t = 28 minutes
Shes spent 28 minutes tap dancing
Answer:

Step-by-step explanation:
we know that
The exponential function is of the form

where
a is the initial value or y-intercept
b is the base or factor growth
r is the rate of change
In this problem we have
looking at the graph
Is a exponential growth function (as the value of x increases the value of y increases)
so

The y-intercept is the point (0,4)
so

substitute

From the graph take the point (1,8)
substitute in the exponential function and solve for b

therefore
The exponential function is equal to
