Actually Welcome to the Concept of the Volumes.
==> Volume is Basically defined as the amount of a substance any shape or an object can hold.
==> Volume just can be tendency of any object to hold maximum amount of Substance inside it.
Step B would be correct because you trying to find the total number of hours she reads in 8 days and not the difference. <span />
Answer:
Hello!!
the point (6, 7) is reflected across the y axis. what are the coordinates of the reflection?
(-6, 7)
Step by Step Explanation:
When reflecting (x, y) over the x axis is (x, -y)
When reflecting (x, y) over the y axis is (-x, y)
Hope this helps!
Y = -1
x = 5

The surface area of a cylindrical can is equal to the sum of the area of two circles and the body of the cylinder: 2πr2 + 2πrh. volume is equal to π<span>r2h.
V = </span>π<span>r2h = 128 pi
r2h = 128
h = 128/r2
A = </span><span>2πr2 + 2πrh
</span>A = 2πr2 + 2πr*(<span>128/r2)
</span>A = 2πr2 + 256 <span>π / r
</span><span>
the optimum dimensions is determined by taking the first derivative and equating to zero.
dA = 4 </span>πr - 256 <span>π /r2 = 0
r = 4 cm
h = 8 cm
