Answer: 31.4cm is the correct answer

Step-by-step explanation:

31.4 cm

d = 2r = (2)(5) = 10

C = πd = 10π = 31.4

Answer:

C = 18.8 cm

Step-by-step explanation:

The diameter is 6 cm

To find the circumference, we use

C = pi*d

C = 3.14 *6

C =18.84 cm

Rounding to the nearest tenth

C = 18.8 cm

If the lengths of the legs of a right triangle are 5 and 12, what is the length of the hypotenuse?

sasho [114]

h - length of the hypotenuse

Use the Pyhagorean theorem:

$h^2=5^2+12^2\\\\h^2=25+144\\\\h^2=169\to h=\sqrt{169}\\\\\boxed{h=13}$

Find the area of the shaded regions. Give your answer as a completely simplified exact value in terms of π (no approximations).

bagirrra123 [75]

Answer:

$27\pi \ cm^{2}$

Step-by-step explanation:

we know that

The area of a circle is equal to

$A=\pi r^{2}$

we have

$r=6\ cm$

substitute

$A=\pi (6)^{2}=36 \pi\ cm^{2}$

Remember that a central angle of $360\°$ subtends for the area of a complete circle

by proportion

Find the area of the circle for a central angle of $270\°$

$\frac{36 \pi}{360} \frac{\ cm^{2}}{degrees}=\frac{x}{270} \frac{\ cm^{2}}{degrees} \\ \\ x=270*36\pi /360\\ \\x=27\pi \ cm^{2}$

Answer: 5, 8

Step-by-step explanation:

The difference between 3 times a number and -8 is BETWEEN 23 and 32

Note: "difference" means subtraction --> 3x - (-8) --> 3x + 8

23 < 3x + 8 < 32

15 < 3x < 24 subtracted 8 from all 3 sides

--> 5 < x < 8 divided 3 from all 3 sides

If a baseball player has 5 hits in 20 at bats, what is the probability in the decimal to the thousandths place that he will get

k0ka [10]

Answer:

$Probability = 0.250$

Step-by-step explanation:

Given

$Hits = 5$

$Bats = 20$

Required

Determine the probability of hit in next at-bat

This question illustrates theoretical probability and the required probability is calculated using:

$Probability = \frac{Events\ Occurrence}{Trials}$

In this case, we have:

$Probability = \frac{Hits}{Bats}$

$Probability = \frac{5}{20}$

$Probability = 0.250$
