Answer :

B) 84 m³

Step by step :

$\boxed{ \bold{volume = \frac{1}{3}\pi {r}^{2} h }}$

$volume = \frac{1}{3} \times 3.14 \times 4 \times 4 \times 5 \\ volume = \frac{1}{3} \times 251.2 \\ volume = 83.73 \: {m}^{3} \\ volume = 84 \: {m}^{3}$

PLEASE HELP .........

Answer:

11860.22 rev/hour

Step-by-step explanation:

The diameter if a cylinder, d = 21.02 inches

Radius, r = 10.51 inches

r = 0.875 feet

The linear speed of a point on the cylinder's surface is 18.12 ft/sec.

We need to find the angular speed of the cylinder.

The relation between the linear speed and the angular speed is given by :

$v=r\omega$

Where

$\omega$ is angular speed

$\omega=\dfrac{v}{r}\\\\\omega=\dfrac{18.12}{0.875}\\\\\omega=20.7\ rad/s$

$\omega=11860.22\ rev/hour$

So, the required angular speed of the cylinder is 11860.22 rev/hour.

What is the value of i^20+1?<br> A. 1<br> B. –1<br> C. –i<br> D. i

lisov135 [29]

ANSWER

${i}^{20} + 1 =2$

EXPLANATION

The given expression is;

${i}^{20} + 1$

Recall that, in complex numbers

${i}^{2} = - 1$

We use this identity to simplify the given expression:

${i}^{20} + 1 =( {i}^{2})^{10} + 1$

This implies that:

${i}^{20} + 1 =( - 1)^{10} + 1$

${i}^{20} + 1 =1+ 1$

${i}^{20} + 1 =2$
