Assuming it is a cylinder,

SA≈ 20734.5 mm^2

This was found by using the formula below.

Answer:

Step-by-step explanation:

f(x)·g(x)=(x³+2x²+3x+1)(4x-5)

= $4x^{4} +8x^{3} +12x^{2} +4x-5x^{3} -10x^{2} -15x-5$

= $4x^{4} +3x^{3} +2x^{2} -11x-5$

B) The number of volume of a cylinder is half of its number of the total surface area.

faust18 [17]

Answer:

$V=179.6cm^3$

Step-by-step explanation:

the volume of a cylinder is given by:

$V=\pi r^2h$

where r is the radius and h is the height.

and the surface area:

$SA=2\pi r^2+2\pi rh$

the first term is the area of the circles and the second term is the area of the body.

since "The number of volume of a cylinder is half of its number of the total surface area." we will have that:

$V=\frac{1}{2}SA$

substitutig the equivalent expressions on each side:

$\pi r^2 h = \frac{1}{2} (2\pi r^2+2\pi r h)$

and we simplify and solve for the height (since is the value we don't know of the cylinder):

$\pi r^2 h = \pi r^2+\pi r h\\\pi r^2h-\pi rh=\pi r^2\\h(\pi r^2-\pi r)=\pi r^2\\h=\pi r^2/(\pi r^2-\pi r)$

we substitute the value of the radius $r=7cm$ , and we get:

$h=\pi (7cm)^2/(\pi (7cm)^2-\pi (7cm))\\h=153.938/(153.938-21.991)\\h=153.938/131.947\\h=1.1666cm$

thus the volume is:

$V=\pi r^2h$

$V=\pi (7cm)^2(1.1666cm)\\V=179.6cm^3$

the relationship between feet and inches is a function. Write an equation that shows how to find the number of inches (n, output

BigorU [14]

Answer: One foot = 12in. Two Feet = 24in. Three Feet = 36in. Four Feet = 48in.

Step-by-step explanation: So there is 12 inches in one foot. In two feet it is just double so 24 inches. In three it is just triple so 36 inches and in four you just do 12 times 4 so 48 inches.
