4 0
Lets get started :)

The Volume formula of a Cylinder is 
V = \pir²h
(r = radius, h = height)

The radius given is 8 and the height is 4, We can plug in the known values

V = \pi(8)²(4)
   = \pi256
   = 256\pi units³ (You can leave the answer in this form)
   ≈ 804.2 units³ (approximately)

Units³ because it is a volume (3D shape)

Which equation is equivalent to x + 8 = 21? (x + 8) × 4 = 21 (x + 8) × 4 = 21 ÷ 4 (x + 8) × 4 = 21 × 2 (x + 8) × 4 = 21 × 4
Drupady [299]

Answer:

(x + 8) × 4 = 21 × 4

Explanation:

x + 8 = 21

21 - 8 = 13

(13 + 8) × 4 = 21 × 4

21 × 4 = 21 × 4

84 = 21 × 4

84 = 84

How much, in total, did Noel spend to cash her three most recent paychecks?
astra-53 [7]

The total amount of money that was spent by Noel to cash her three (3) most recent paychecks is equal to $10.99.

<h3>What is a paycheck?</h3>

A paycheck can be defined as a financial document that is issued by an employer to an employee as payment for the work done over a period of time.

<h3>How to calculate the amount spent.</h3>

From the table, we can see that the amount of money charged by the bank as check processing fee is equal to $1.99, as well as 1.99% (0.0199) of the amount being cashed by a customer.

Thus, we would compute the amount of money spent by Noel as follows:

Noel = (0.0199 × 100.53) + (0.0199 × 119.38) + (0.0199 × 122.52) + (1.39 × 3)

Noel = 2.00 + 2.38 + 2.44 + 4.17

Noel = $10.99.

A skydiver is falling at approximately 28 feet per second. Find the skydiver's change in altitude
Free_Kalibri [48]

9514 1404 393

Answer:

  -140 feet

Step-by-step explanation:

The relation between speed, distance, and time can be written ...

  distance = speed × time

  distance = (28 ft/s)(5 s) = 140 ft

In 28 seconds, the skydiver changed position by 140 feet. Since the direction is presumed to be down (falling), the change in altitude is -140 feet.
