Answer:

V ≈ 198 m³

Step-by-step explanation:

The volume (V) of a cylinder is calculated as

V = πr²h ( r is the radius and h the height )

Here diameter = 6, then radius r = 3 and h = 7 , then

V = 3.14 × 3² × 7 = 3.14 × 63 ≈ 198 m³ ( to the nearest whole number )

A rocket is shot in the air at an initial velocity of 12 800 miles per hour. If 1 mile is equal to 5 280 feet, then what is the

Natasha_Volkova [10]

Answer:

GIVEN,

Initial velocity of the rocket = 12800miles/hour

1 mile = 5280 feet

Initial velocity of the rocket in miles/second = (12800*5280)/60*60 feet/second = 18773.33333...feet/second.

What is the measure of o

Helga [31]

Answer:

Step-by-step explanation:

We need the formula for arc length (in radians) to solve this problem. The formula is:

$s=r \theta$

Where

s is the arc length

r is the radius of the circle

$\theta$ is the intercepted angle

In this diagram, we can see that $\theta$ is beign intercepted by the big arc with measure 20 cm. So arc length, s, is 20

Also, if we look, we see that the radius is 5 cm, so r = 5

Now, we substitute into formula and find $\theta$ :

$s=r\theta\\20=5\theta\\\theta=\frac{20}{5}\\\theta=4$

This is given in radians, so $\theta$ is 4 radians

D is the correct answer choice.
