Surface area question:

Mathematics
1 answer:
Dafna1 [17]3 years ago
3 0

Answer:

190π (not part of the answer choices)

Step-by-step explanation:

The surface area of a cylinder can be found using the formula below:

SA=2\pi r^2+\pi dh where r is the radius of the base, d is the diameter of the base and h is the height of the cylinder.

Plug in the given values

SA=2\pi (\frac{10}{2}) ^2+\pi (10)(14)\\SA=2\pi (\frac{100}{4})+140\pi\\SA=2\pi (25)+140\pi\\SA=50\pi+140\pi\\SA=190\pi

Therefore, although this answer isn't one of the choices, the surface area of the cylinder is 190π.

I hope this helps!

There are 8 members on the student council. A committee consisting of 2 members is to be made. How many different committees are
wlad13 [49]

Answer

28 committees

Explanation:

The total number of members = 8

We want to make a committee of 2 members

We will be applying the combination concept

\begin{gathered} \text{let n = 8 and r = 2} \\ ^nC_r\text{ = }\frac{n!}{(n\text{ - r)!r!}} \\ ^8C_2\text{ = }\frac{8!}{(8\text{ - 2)!2!}} \\ ^8C_2\text{ = }\frac{8!}{6!2!} \\ ^{8_2}C\text{ = }\frac{8\text{ x 7 x 6 x 5 x 4 x 3 x 2 x 1}}{6\text{ x 5 x 4 x 3 x 2 x 1! 2 x 1}} \\ ^{8_{}}C_2\text{ = }\frac{8\cdot\text{ 7}}{2} \\ ^{8_{}}C_2\text{ = 28 committees} \end{gathered}

Therefore, 28 committees can be formed

Nuetrik [128]

Answer:

  36.9°

Step-by-step explanation:

The relevant trig relation is ...

  Cos = Adjacent/Hypotenuse

  cos(x) = 8/10 = 0.8

The inverse trig function is used to find the angle:

  x = arccos(0.8) ≈ 36.9°
