Nady [450]
Answer: V=9651 ft^3

Explanation: This is a volume question and the formula for volume of a cylinder is πr^2h.

The radius is the diameter divided by 2, which is 8.

We can put the equation in terms of π by doing π*(8^2*48)=3072π.

Solving this gives us about 9650.972632, which you can round to get 9651.

Find the length of the bold arc. Round to the nearest tenth and use 3.14 or the pi button on your calculator for pi.
Elanso [62]

Answer:

8π yards

Step-by-step explanation:

A circle subtends a total angle of 360 ° from its center.The length of an arc is directly proportional to the angle it subtends from the circle's center. The arc's length can therefore be calculated as:

C=πd=2πr

Where C is circumference, d is diameter and r is radius. Given r as 16 yards then the arc length which is equivalent to circumference is given as

C=\frac {90}{360}*2*\pi*16=8\pi

Wallace took out a $5,000 loan for six years. He is being charged 4 percent interest, compounded annually. Calculate the total a
statuscvo [17]
Wallace will pay $6,325 after 6 years.

Given:
Principal = 5,000
interest rate = 4%
Term = 6 years

Compound Interest means that the interest earned will also be earning its own interest.

Compound Interest = Principal x (1+r)^t
C.I. = 5,000 x 1.04⁶
C.I. = 5,000 x 1.265
C.I. = 6,325  TOTAL AMOUNT HE WILL PAY.

6,325 - 5,000 = 1,325 interest for 6 years.
