A cylinder has a radius of 12m and a height of 8m. What is the approximate surface area of the cylinder? use 3.14 for Pi.

Answers

Answer 1

Answer: Surface Area = 2 × π × r × (r+h). So 2 × π × 12 × (12+8). Then 2 × π × 12 × 20. And then 480 π. And your answer is about 1507.

Answer 2

Answer: Simple, A=2πrh+2πr²=2*π*12*8+2*π*12²=1507.96447m². If you want to round your answer, it would be 1507.96m²

7. Two fields at a state park arfields are 8 centimeters ap
ta state park are 1,000 meters from each other. On a map, the two
re o centimeters apart. What scale is the map using?

Answers

Answer:

$The$ $map$ $is$ $using$ $a$ $1cm:125 m$ $scale$

Step-by-step explanation:

To figure this out, we must use the scale of the map as a unit.

So we first figure out how many meters are for each centimeter on the map.

" Two fields at a state park are fields are 8 centimeters ap(?)ta state park are 1,000 meters from each other."

Set up the ratio:

$(1000)/(8) = (x)/(1)$

Cross multiply:

$8x$ = $1000$

Meaning:

$x = (1000)/(8)$

1000/8

==> 125

x = 125

Meaning that for every centimeter there is 125 meters

1cm = 125m

A spinner is divided into many sections of equal size. Some sections are red, some are blue, and the remaining are green. The probability of the arrow landing on a section colored red is 11 over 20. The probability of the arrow landing on a section colored blue is 6 over 20. What is the probability of the arrow landing on a green-colored section? 6 over 20 3 over 20 9 over 20 17 over 20

Answers

We have 3 sections.

$\sf~Red=(11)/(20)$

$\sf~Blue=(6)/(20)$

So the entire spinner is divided into $\sf20$ sections.

Since we only have 3 sections(red, blue, green) we can add red and blue, and subtract 1 or 20/20.

$\sf(11)/(20)+(6)/(20)\rightarrow(11+6)/(20)\rightarrow(17)/(20)$

Subtract:

$\sf(20)/(20)-(17)/(20)=\boxed{\sf(3)/(20)}$

So the probability that the arrow landing on a green-colored section is $\sf(3)/(20)$ .

Answer:

3 over 20
