Answer:
Why? You have it there. Anyways, here's the step=by step.
Step-by-step explanation:
The equation for the volume of a cylinder is
V= π × height × radius²
or
V=π × r² × h
What you'll do then is multiply
11.1 × 34.4² × 3.14
Type that in a calculator and boom, you got your answer!
You should multiply 2 at a time and not try to do them at the same time also if the fraction numbers a high you can cross simplify the numbers so multiplying them won't be as hard. so, for example, 8/12*16/36*50/100 you can simplify 8/12 to 2/3 16/36 to 4/9 50/100 to 1/2 then you can multiply 2/3*4/9 and then 8/27*1/2 to equal 8/54 and you can still simplify 8/54 to 4/27
Answer:
a
Step-by-step explanation:
<em>Greetings from Brasil...</em>
a)
Let's just use Pythagoras
L² = X² + (X - 7)²
<h3>L = √(2X² - 14X + 49)</h3><h3 />
b)
If L = 13, then what is the value of X ???
L² = 2X² - 14X + 49
2X² - 14X - 120 = 0
X = 12 or X = - 5
<em>(The distance cannot be negative, so X = 12)</em>
Answer:
15
Step-by-step explanation:
9^2+12^2=c^2 use pythagorean thereom
225=c^2 use radical to solve
c=15
