Answer:
3 Years
Step-by-step explanation:
7000*22% = 1540
4620/1540 = 3
1540 = the yearly interest
so it will take 3 years of $1540 of interest to get $4620.
Normally you would also have to take into account the interest plus the base varible but since it specifically says 7000 it makes it a simple problem.
hope this helped
Original Circle Area = 45
A = pi * r^2
Plug in what we know:
45 = 3.14 * r^2
Divide 3.14 to both sides:
14.3312102 = r^2
Find the square root of both sides:
r = 3.78565849
Find 2/3 of this:
2/3 * 3.78565849 = 2.52377233
So this is the radius of the newly dilated circle.
A = pi * r^2
A = 3.14 * 2.52377233^2
A = 3.14 * 6.36942677
A = 20
So the area of the newly dilated circle is 20 square inches.

Answer:
553.0 in³
Step-by-step explanation:
(please see attached for reference)
Assuming you are asked to find the volume,
the volume of the cylinder is given by
V = πr²h
where,
π=3.142
r = given as 4 inches
h = given as 11 inches
Substituting these values into the formula,
V = πr²h
V = 3.142 x 4² x 11
= 552.99
= 553.0 in³ (rounded to nearest tenth)
