Formula for volume:
πr^2(h/3)
Diameter divided by 2 is the radius
18/2 = 9
radius: 9 units
Use pythagorean theorem to find height
x^2 + 9^2 = 15^2
225 - 81 = 144
x^2 = 144
x = 12
height: 12 units
Plug these number in the volume formula.
Thus, it should be looking as:
π9^2(12/3) = 1017.88
Answer:
1017.88 
Answer:
Step-by-step explanation:
<u>We know that:</u>
- Length = (4m + 7)
- Breadth = (3m + 2)
The perimeter of a shape is the sum of its boundaries. Let's represent perimeter as p.
<u>Solution:</u>
- p = (4m + 7) + (4m + 7) + (3m + 2) + (3m + 2)
- => p = 2(4m + 7) + 2(3m + 2)
Hence, the algebraic expression on how to find the perimeter is 2(4m + 7) + 2(3m + 2).

Step-by-step explanation:
Rational expressions are often used in combining rates of work. Therefore, it's true.
<h3>What is rational expression?</h3>
It should be noted that a rational expression is simply defined by a rational fraction.
They're are used in combining rates of work. Fir example, if Mr John performs 1/2 of his work and does 1/3 on another day. This can be expressed as:
= 1/2 + 1/3
= 5/6
