Answer:

V =94.2 cm^3

Step-by-step explanation:

The volume of a cone is

V = 1/3 pi r^2 h

The radius is 3 and the height is 10

V = 1/3 ( 3.14) 3^2 * 10

V = 1/3 (3.14) *9(10)

V =94.2 cm^3

Answer:

94.2 cm³

Step-by-step explanation:

The volume of a cone is

1/3 x h x π x r²

Plug in the values!

1/3 x 10 x 3.14 x 3²

1/3 x 10 x 3.14 x 9

3 x 10 x 3.14

30 x 3.14

94.2 cm³

Use the circuits shown to solve each of the following:
Harlamova29_29 [7]

Answer:

1. R = 8 ohms 2. V = 32 volts

Step-by-step explanation:

<h3>1. We have,</h3>

Voltage, V = 16 V

Current, I = 2 A

We need to find the resistance of the circuit. Using Ohm's law,

V = IR

So,

R=\dfrac{V}{I}\\\\R=\dfrac{16}{2}\\\\R=8\ \Omega

2. Current, I = 8 A

Resistance, R = 4 ohms

We need to find the voltage of the circuit. Using Ohm's law again,

V = 8 × 4

V = 32 volts

Hence, this is the required solution.

For males in a certain town, the systolic blood pressure is normally distributed with a mean of 110 and a standard deviation of
oksian1 [2.3K]

The interval of systolic blood pressure lie between 102 and 118.

<h3>What is systolic blood pressure?</h3><h3>Blood pressure is measured using two numbers: The first number, called systolic blood pressure, measures the pressure in your arteries when your heart beats. The second number, called diastolic blood pressure, measures the pressure in your arteries when your heart rests between beats.</h3>

Here, mean blood pressure is 110

and standard deviation is 8

By z table, for 68%,

-1 < z < 1

-1 < (x - μ) / σ < 1

on multiply by σ, we get

-σ < x-μ < σ

on adding μ, we get

-σ + μ < x < σ + μ

-8 + 110 < x < 110 + 8

102 < x < 118

Thus, the interval of systolic blood pressure lie between 102 and 118.

Pleaseeee asapppppp asapppppp
Hatshy [7]

Answer:

7.07

Step-by-step explanation:

Angle M is 63 degrees because all 3 angles must add to 180.

Now use the law of sines:

sin(90)/x = sin(63)/6.3

Cross multiply: 6.3 sin (90) = x sin (63)

Divide by sides by sin (63): (6.3 sin (90))/sin (63) = x

Use a calculator: 7.07
