To solve this we are going to use the formula for the area of a circle:
where
is tte radius of the circle
We can infer that the bases of our cylinder are circles with 2 in radius, so
. Since we have tow circles, we are going to multiply the area by 2:
We can conclude that the <span>the combined area of the two bases of the cylinder is </span><span>
25.12 in.2</span>
The answer to the problem is 24
Make y the subject:
2x+y=-5
2x+5=-y
y=-2x-5
y=-2x+2 is the answer as the slope does not change but the y intercept does
Answer: 74
Step-by-step explanation:
Lets say the four even numbers are 2x - 4, 2x - 2 , 2x , 2x + 2
The sum would be
8x - 4 = 284
x = 36
Therefore, the smallest number is 2 * 36 - 4 = 68
The consecutive even numbers are 68, 70, 72, 74 and 74 is the largest.
