The volume of a cylinder is

V = (1/3) π (radius)² (height) .

It doesn't matter whether it's straight, or leaning over like this one.

V = (1/3) π (4 m)² (6 m)

V = (1/3) π (16 m²) (6 m)

V = (1/3) π (96 m³)

==> V = 32 π m³

Volume = 1/3 * pi * r^2*h
= 1/3 + pi * 4*2 * 6
= 8pi m^3

Write an equation of the line perpendicular to the given line that contains P.

Yakvenalex [24]

Answer:

y +5 = -1/3(x -3)

Step-by-step explanation:

The slope of the given line is 3. The slope of the perpendicular line is the negative reciprocal of that, -1/3. Then the point-slope equation is ...

y -y1 = m(x -x1) . . . . line with slope m through point (x1, y1)

y -(-5) = -1/3(x -3)

y +5 = -1/3(x -3)

Write the sum of the numbers as the product of their GCF and another sum.

8090 [49]

Answer:

See explanation

Step-by-step explanation:

1. Find the GCF of 40 and 44:

$40=\underline{2\cdot 2}\cdot 2\cdot 5\\ \\44=\underline{2\cdot 2}\cdot 2\cdot 11\\ \\GCF(40,44)=2\cdot 2=4$

So,

$40+44=4\cdot 10+4\cdot 11=4\cdot (10+11)$

2. Find the GCF of 13 and 52:

$13=\underline{13}\\ \\52=2\cdot 2\cdot \underline{13}\\ \\GCF(13,52)=13$

So,

$13+52=13\cdot 1+13\cdot 4=13\cdot (1+4)$

3. Find the GCF of 15 and 81:

$15=\underline{3}\cdot 5\\ \\81=\underline{3}\cdot 3\cdot 3\cdot 3\\ \\GCF(15,81)=3$

So,

$15+81=3\cdot 5+3\cdot 27=3\cdot (5+27)$

4. Find the GCF of 64 and 28:

$64=\underline{2\cdot 2}\cdot 2\cdot 2\cdot 2\cdot 2\\ \\28=\underline{2\cdot 2}\cdot 7\\ \\GCF(64,28)=2\cdot 2=4$

So,

$64+28=4\cdot 16+4\cdot 7=4\cdot (16+7)$
