Answer:
45
Step-by-step explanation:
<span>So we want to know how much sand can we store in a cylinder that has height h=5 feet and a radius r=0.5 feet if we need 0.48 ft^3 of sand for a batch of mortar. That is, how many batches of mortair can we make from the sand in the cylinder. So lets first calculate the volume V of the cylinder: V=r^2 * pi * h=3.925 in^3. Now lets divide the volume by 0.48 so we get the unit od sand needed for one batch od mortar: V/0.48= 8.177083. The nearest whole number is 8. </span>
You plug in a 3 wherever you see an x
2x^3-4x^2+6x
2(3)^3-3(3)^2+6(3)
2(27)-3(9)+18
54-27+18
27+18
=45
Hope this helps
156 ft. Multiply 13 by 12, there is 1 inch= 13 ft
These cannot make any types of triangles.
