marshall27 [118]

the volume of the cylinder is 572.27 cm³

Explanation:

Given:

radius of the cylinder = 4.5cm

height = 9cm

To get the volume of the cylinder, we will use the formula:

$\begin{gathered} Volume\text{ = \pi r^^b2h} \\ where\text{ \pi= 3.14} \\ r\text{ = radius, h = height} \end{gathered}$ $\begin{gathered} Volume\text{ of the cylinder = 3.14 }\times\text{ 4.5}^2\text{ }\times\text{ 9} \\ Volume\text{ of the cylinder = 3.14 }\times\text{ 182.25} \\ \\ Volume\text{ of the cylinder = 572.265 cm}^3 \end{gathered}$

To the nearest hundredth, the volume of the cylinder is 572.27 cm³

a set if cards includes 20 yellow cards, 16 green cards, and 24 blue cards. what is the probability that a blue card is chosen a

devlian [24]

Answer:

2/5

Step-by-step explanation:

Probability is the chance that a certain event occurs out of the total events.

Here, the event of "choosing a blue card". The total events are just "choosing any card".

There are 24 blue cards and 24 + 20 + 16 = 60 cards in total. So, we just take 24 and divide it by 60: $\frac{24}{60}$ . Simplifying, we get:

$\frac{24}{60} = \frac{2}{5}$

Thus, the answer is 2/5.

Hope this helps!

Find the surface area of a square pyramid with side length 4 mi and slant height 5 mi.

andriy [413]

Answer:

SA = 56 sq mi

Step-by-step explanation:

SA = area of base + 1/2(perimeter of base)(slant height)

SA = 16 + 1/2(16)(5)

SA = 16 + 8(5)

SA = 16 + 40
