Answer: V = πr 2 h
Step-by-step explanation:
To calculate the volume of a cylinder, you must know its height and the radius of the circular base (the distance from the center of the circle to its edge) at the top and bottom. The formula is V = πr 2 h, where V is the Volume, r is the radius of the circular base, h is the height, and π is the constant pi.
Answer:
We have:
7 + 4 = 11;
11 - 7 = 4;
11 x 2 = 22;
4 x 4 = 16;
22 - 16 = 6;
Finally, 8 x 6 = 48;

Answer:
length=30 ft breadth=20 ft
Step-by-step explanation:
let lenght be x then breadth will be 2/3x
now, area=lenght×breadth
=>600 =(x×2/3x)
=>600=2/3x^2
=>x^2=900
=>x=30 (ft)
now length will be 30 ft
breadth will be 30×2/3 (ft) =20(ft) ✌️

Step-by-step explanation:
We will have to expand first then we simplify.
<u>Expand</u>
You will have to distribute the 2 over the x & 7 and the 3 over the x & 1 respectively.
<u />
<u />
<u>Simplify</u>
You will have to add 2x & 3x together and 14 & 3 together.
