Answer: 1809.792\ m^3

Step-by-step explanation:

Given

The diameter of the cylinder is d=12\ cm

height of the cylinder is h=16\ cm

The volume of a cylinder is given by

V=\pi r^2h

Insert the values

\Rightarrow V=\pi \times 6^2\times 16\\\Rightarrow V=3.142\times 576\\\Rightarrow V=1809.792\ m^3

The volume of the cylinder is 1809.792\ m^3

Can someone pls explain to me how to do this (^。^)

Answer:

Area: \frac{8}{15} feet²

Perimeter: \frac{44}{15} =2 \frac{14}{15} feet

Step-by-step explanation:

The <u>formula of finding the </u><u>area</u><u> of a rectangle</u> or square is <u>width multiplied by length</u>.

The <u>formula of find the </u><u>perimeter</u><u> of a rectangle</u> or square is <u>width+width+length+length</u>

Area: \frac{4}{5} *\frac{2}{3} = \frac{8}{15} feet²

Perimeter:

\frac{4}{5} +\frac{4}{5} +\frac{2}{3} +\frac{2}{3} =

\\\\\frac{12}{15} +\frac{12}{15} +\frac{10}{15} +\frac{10}{15} =\\\\\frac{24}{15} +\frac{20}{15} =\\

\frac{44}{15} =2 \frac{14}{15}

Given 15 cot A = 8, find sin A and sec A.​
pogonyaev

Answer:

sin A = 15/17

sec A = 17/8

Step-by-step explanation:

15 cot A = 8

First get cot A alone.

cot A = 8 / 15

Since cot is the reciprocal of tan then flip 15 and 8.

tan A = 15 / 8

Now you have the opposite and adjacent sides, just find the hypotenuse with Pythagorean's theorem

15^2 + 8^2 = 289

\sqrt{289} = 17

Now that you have all the sides use the opposite and hypotenuse to get sine and the adjacent and hypotenuse to get cosine then flip to get secant.

sin A = 15/17

cos A = 8/17

sec A = 17/8
