What is the surface area of the cylinder shown below? Use 3.14 for π. A. 660 cm2 B. 863 cm2 C. 353.25 cm2 D. 785 cm2

Answers

Answer:

602.88cm²

Step-by-step explanation:

Find the image of the cylinder attached

Surface area of a cylinder = A=2πrh+2πr²

r is the radius = 4cm

Height h = 20cm

Substitute

A = 2πr(r+h)

A = 2π(4)(4+20)

A = 8π(24)

A = 192π

A = 192(3.14)

A = 602.88cm²

Hence the surface area of the cylinder is 602.88cm²

Suppose that the probability that your

What is the probability that your
mail
will be delivered before 2 pm for two
consecutive days? Give your answer as
a decimal.

Answers

Answer:

The probability is 0.81

Step-by-step explanation:

The probability we want to find here is that;

the mail was delivered before 2 pm the first day and also delivered before 2 pm the next day

what we have to do here is to

multiply together, the probability in the two cases (for both days)

So we have this as:

0.9 * 0.9 = 0.81

Answers

Answer:

my mother say it is B. she is good at math

Answer: A

Step-by-step explanation:

Answer A is a lie. The most obvious reason being the other two statements can be proven because the y intercept of the exponential IS (0, 1). Secondly, the point (-2, 4) CAN be found on the graph. Option A is the lie because if you look, for x = 10, y = 0. Therefore, the statement that for very large values of x the exponential has very large values of y, is a lie.

find the measure of the arc AC

Answers

i get mABC = 270°
Step-by-step explanation:
This is fairly straight forward once you the right angle symbol for the arc AC. Also realizing the 148° for mAB is not needed for this question. The 148° for mAB would be useful if you wanted to calculate arc mBC.
Remember there are 360° in a circle.
The arc mAC is 90°
The arc mABC is the rest of the circle. is the arc from A to B to C
arc ABC + arc AC is the full circle 360°
mABC + mAC = 360° mAC = 90°
mABC + 90° = 360° - 90° from both sides
mABC = 360° - 90°
mABC = 270°

what does 45=-3x tell me

Answers

Answer:  x = -15

Hope this helps :)

Answer:

x = -15

Step-by-step explanation:

[One step multiplication problem]

When solving a one-step multiplication problem the easiest thing to do would be to divide the 'answer' (in this case, 45) by the coefficient (in this case, -3). A negative number times a negative number is a positive number, so x would be a negative number. 45 divided by -3 is -15.

So, x = 15.
