Mathematics

Serjik [45]3 years ago

Answer:

C = 2πr.

Step-by-step explanation:

To calculate the circumference of a circle, use the formula C = πd, where "C" is the circumference, "d" is the diameter, and π is 3.14. If you have the radius instead of the diameter, multiply it by 2 to get the diameter. You can also use the formula for circumference of a circle using radius, which is C = 2πr.

Haleigh split 4/9 of a gallon of juice into 8 cups. How much juice was in each cup?
Brut [27]

━━━━━━━☆☆━━━━━━━

▹ Answer

<em>1/18 of a gallon of juice in each cup.</em>

▹ Step-by-Step Explanation

Since we have 4/9 of a gallon of juice for 8 cups, we will divide to find the amount of juice in each cup.

\frac{4}{9} / 8

Since this operation is division, we have to change 8 to it's reciprocal which is 1/8:

\frac{4}{9}/ \frac{1}{8} = \frac{4}{72} = \frac{1}{18}

Our final answer will be 1/18 of a gallon of juice in each cup.

Hope this helps!

A cylindrical tank has a height of 10 feet and a radius of 4 feet. Jane fills the tank with water at a rate of 8 cubic feet per
ki77a [65]

<u>Given</u>:

A cylindrical tank has a height of 10 feet.

The radius of the cylindrical tank is 4 feet.

Jane fills the tank with water at a rate of 8 cubic feet per minute.

We need to determine the time it will take for Jane to completely fill the tank without overflowing it.

<u>Volume of the cylinder:</u>

The volume of the cylinder can be determined using the formula,

V=\pi r^2 h

Substituting the values, we have;

V=(3.14)(4)^2(10)

V=(3.14)(16)(10)

V=502.4

Thus, the volume of the cylinder is 502.4 cubic feet.

<u>Time taken:</u>

The time taken can be determined using the formula,

Time = \frac{Volume}{Rate \ of\  filling}

Substituting the values, we have;

Time = \frac{502.4}{8}

Time = 62.8

Thus, Jane takes 62.8 minutes to completely fill the tank without overflowing it.
