The answer is 6 1/4, because if you making 1/2 = 2/4, 2 + 3 = 5, the 4 stays the same, so its 5 5/4, and to make it proper, you make it 6 1/4
The formula is y2 - y1/x2 - x1. The answer would be 3/4 once simplified.
First we want to know the surface of the circle, which is

with r representing the radius. In this case


To find the volume of the cylinder we have to multiply this outcome with the height.



Hence, the volume of the cylinder is about 5024 cubic cm.
Answer:
+ 8
Step-by-step explanation:
To rationalise the denominator, multiply the numerator and denominator by the conjugate of the denominator.
The conjugate of
- 8 is
+ 8 , then

Answer:
There are only 3 differences perform
Step-by-step explanation:
I. If x is negative, y is negative then the answer is possitive
eg. x is -2, y is -3
-2 × -3 = 6
II. If x is negative, y is positive then the answer is negative
eg. x is -1, y is 2
-1 × 2 = -2
III. If x is possitive, y is possitive then the answer is positive
eg. x is 2, y is 5
2 × 5 = 10
Alt. No matter how long x, y, z, a, b there always apply only 3 rules above. Multiply or Devide are the same rule.
Ask me for anything :D
