A cylinder has an 18-inch diameter and is 15 inches tall. It is filled to the top with water. A 6-inch-diameter ball is
Goshia [24]

water in cylinder = 1.179π in³

<h3>Further explanation</h3>

Volume is a derivative quantity derived from the length

The unit of volume can be expressed in liters or milliliters or cubic meters

The volume of the cylinder

V = πr².h

the volume of ball

V= 4/3πr³

volume of cylinder

\tt V=\pi.9^2.15=1215\pi

volume of the ball

\tt V=\dfrac{4}{3}\pi.r^3\\\\V=\dfrac{4}{3}.\pi.3^3=36\pi

water in the cylinder

V cylinder - V ball

\tt 1215\pi-36\pi=1179\pi

The revenues and expenses of Sentinel Travel Service for the year ended August 31, 2019, follow: Fees earned $745,515 Office exp
kvv77 [185]

Answer:

Step-by-step explanation:

What I will do is attach a picture of the income statement prepared, and explained the process and figures gotten, first we start with writing the Revenue with the year 2019, for the revenue, the only value given is the Fees earned, then after Revenue, we go to expenses, where we have Office, Miscellaneous, and wages, then we find the total of that, then after this we go to net income before Taxes, which is the difference with the total revenue and total expense, which is $745,515 - $544,225 = $201,290

Then we find the income tax expenses and we assume that tax is 40% of your profit, which is 40% of $201,290 = 40/100 x 201290 = $80,516

Then we find the net income which is the income tax expense subtracted from the net income before tax

201290 - 80516 = 120,774

Find the picture attached from the income statement

Can you please help with this

First you want to turn both fractions into improper fractions. So 1 4/7 would now be 11/7 because 1 x 7 + 4 is 11. And -1 4/8 will now be -12/8 because 1 x 8 + 4 is 12. Now you must find the common denominator. 8 x 7 is equal to 56 so the common denominator is 56. So now we are adding 11/56 + (-12/56). 11 plus 12 is 23. So we have 23/56. 23 can go into 56 two times because 23 x 2 = 46. There is 10 left over so our final answer is -2 10/56. In simplest form our answer would be -2 5/28

Pierce draws a circle with a radius of 3 centimeters. Ginna draws a circle with a radius that is twice as long as the radius of
erastova [34]

Answer:

Circumference of the circle drawn by Ginna is twice the Circumference of the circle drawn by Pierce.

Step-by-step explanation:

Given:

Radius of the circle drawn by Pierce = 3 cm

We need to find circumference of gianna's circle compare with the circumference of Pierce's circle.

Solution:

Radius of the circle drawn by Pierce = 3 cm

so we will find the Circumference of circle drawn by Pierce.

Now we know that;

Circumference of the circle is given by 2 times π times radius of the circle.

framing in equation form we get;

Circumference of the circle drawn by Pierce = 2\pi\times 3=6\pi\ cm

Now Given:

Ginna draws a circle with a radius that is twice as long as the radius of pierce's circle.

So we can say that;

radius of the circle drawn by Ginna is equal to 2 times radius of circle drawn.

so we can say that;

radius of the circle drawn by Ginna = 2\times3  = 6\ cm

Circumference of the circle drawn by Ginna = 2\pi\times 6=12\pi\ cm

Now we can see that;

Circumference of the circle drawn by Ginna is 12\pi \ cm while Circumference of the circle drawn by Pierce is 6\pi \ cm

So we can say that;

Circumference of the circle drawn by Ginna is twice the Circumference of the circle drawn by Pierce.
