Remark
You have to read this carefully to know what way to write it.
One way you could write it would be
20 * x = 18 where x is the fraction. Now all you need do is divide.
Divide both sides by 20
20/20 * x = 18/20

But you should reduce this fraction. The way to do that is to factor 18 and 20 into primes.
18: 2 * 3 * 3
20: 2 * 2 *5
Cancel out the Highest common factor or 2.
You are left with
<<<< Answer
Answer: 1018
Step-by-step explanation:
A = pi x r squared x height
= 3.14 x 6 squared x 9
= 1017.88
= 1018 to nearest whole number
Answer is 1.538
Using (x1,y1)(x2,y2)
x1=0
Y1=2
X2=5.2
Y2=10
Answer: 45 degrees
explanation: if x is in a square with all right angles that is 90 degrees and the entire square is divided in half it would be 45 degrees with the other corresponding angle 45 degrees minus 90 it is also 45 degrees
