Answer:

A. Volume = 4,523.9 mm³ (cubic mm)

B. Surface area = 1,658.76 mm² (square mm)

Step-by-step explanation:

A. Lest's calculate the volume of the cylinder:

r = 12 mm, h = 10 mm

Volume = π * r² * h

Volume = 3.1416 * 12² * 10

Volume = 3.1416 * 144 * 10

Volume = 4,523.9 mm³

B. Let's calculate the surface area of the cylinder:

Surface area = 2π * r * h +2π * r²

Surface area =2π * 12 * 10 + 2π * 12²

Surface area = 6.2832 * 120 + 6.2832 * 144

Surface area = 753.98 + 904.78 = 1,658.76 mm²

Carlos has a fair die and a number cube. He will flip the fair die one time and roll the number cube one time. What is the proba

saul85 [17]

Answer: 0.42 and 5 outcomes.

Step-by-step explanation:

i guess that carlos has a fair coin and a number cube.

the probability can be calculated as the number of outcomes that we want divided the total number of outcomes.

The coin has two possible outcomes, heads and tails, then the probability of getting heads is p1 =1/2

the number cube has 6 numbers, 5 of those 6 numbers are greater than 1, then the probability of getting a number greater than 1 is p2 =5/6

the joint probability is the product of those two:

P = 1/2*5/6 = 5/12 = 0.42

The combinations that include heads and number greater than 1 are 5 combinations:

Heads and 2

Heads and 3

Heads and 4

Heads and 5

Heads and 6.

Answer:

The length of the long side is 147 ft

The length of the short side is 30 ft

Step-by-step explanation:

L=5s-3

s= 324-2L

324=2(5s-3)+s

distribute

324=10s-6+s

simplify

324=11s-6

add 6 to both sides

330=11s

divide by 11

30=s

Plug in the s value to determine the length of the long side

After a 80% reduction, you purchase a new washing machine on sale for $56.

Daniel [21]

80% = $56
1% = $56/80 = $70
100% = $70 * 100 = $700
Original price = $700
Hope this helps.

Given triangle ABC with m M

sammy [17]

9514 1404 393

Answer:

49°

Step-by-step explanation:

The sum of angles in a triangle is 180°.

∠A +∠B +∠C = 180

(x +32) +(x +41) +(3x +22) = 180 . . . . angles assumed to be in degrees

5x +95 = 180

5x = 85

x = 17

x +32 = 49 . . . . measure of ∠A
