1 answer:

3 0

To answer the question above, convert the given measurement of the angle in revolutions. The conversion factor is 1 revolution is equal to 2π or 6.28 radians.
(16.2 rev) x (6.28 rad / 1 rev) = 101.736 rad
Then, divide the value obtained with time which is 7. The answer is approximately 14.53 rad/s.

A regular hexagon has an area of 750.8cm². The side length is 17cm. Find the apothem.

larisa86 [58]

The formula for determining the apothem of regular hexagon is s/2tan(180/n) , where 's' is any side length of regular hexagon and 'n' is the number of sides of regular hexagon.
So, apothem = 17/2tan(180/n)
= 17/2tan(30)
= 17/1.15
= 14.78 units
Therefore, the measure of apothem of the regular hexagon is 14.7 units.
B is the right answer.

I need help! what is 75 equals 6 multiplied by w

mart [117]

Answer:

w = 12.5

Step-by-step explanation:

Write an equation 75 = 6 * w or 75 = 6w

Then divide both sides by 6

you'll end up with w equals 12.5
