The radius of a cylindrical construction pipe is 2.5 ft. If the pipe is 28 ft long, what is its volume?

atroni [7]

Answer:

V = 549.5 ft³

Step-by-step explanation:

The formula for the volume, V, of a cylinder of radius r and length h is

V = πr²h.

Substituting 2.5 ft for r and 28 ft for h, we get the volume

V = 3.14(2.5 ft)²(28 ft), or

V = 549.5 ft³

Andre45 [30]

Answer:

1,518,000 committees.

Step-by-step explanation:

We have been given that the judiciary committee at a college is made up of three faculty members and four students. Ten faculty members and 25 students have been nominated for the committee.

We will use combinations for solve our given problem.

$^nC_r=\frac{n!}{r!(n-r)!}$ , where,

n = Number of total items,

r = Items being chosen at a time.

$^{10}C_3\cdot ^{25}C_4=\frac{10!}{3!(10-3)!}\cdot \frac{25!}{4!(25-4)!}$

$^{10}C_3\cdot ^{25}C_4=\frac{10!}{3!*7!}\cdot \frac{25!}{4!*21!}$

$^{10}C_3\cdot ^{25}C_4=\frac{10*9*8*7!}{3*2*1*7!}\cdot \frac{25*24*23*22*21!}{4*3*2*1*21!}$

$^{10}C_3\cdot ^{25}C_4=10*3*4\cdot 25*23*22$

$^{10}C_3\cdot ^{25}C_4=120\cdot 12650$

$^{10}C_3\cdot ^{25}C_4=1,518,000$

Therefore, 1,518,000 judiciary committees could be formed at this point.
