Guanglei works in urban landscaping design. a delivery truck arrived, pouring a cone-shaped pile of gravel 6 feet high with a diameter at the base of 8.2 feet. how much gravel was delivered? (use π=3.14)

105.57 cubic feet.

Step-by-step explanation:

A delivery truck arrived in the construction site and pouring a cone-shaped pile of gravel 6 feet high with a diameter at the base of 8.2 feet.

Therefore, the volume of the cone shaped pile is , where r = feet and h = 6 feet.

Hence, V = cubic feet.

So, 105.57 cubic feet of gravel was delivered. (Answer)

f(x) is the value of the function. b is the value of the function when x equals zero or the y-coordinate of the point where the line crosses the y-axis in the coordinate plane.

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%
