Answer:

6433.98 ft

Step-by-step explanation:

In order to find what 25% of the tank's capacity is, we know to know the full capacity of the tank then take 25% of that. The volume formula for a right circular cone is

$V=\frac{1}{3}\pi r^2h$

We have all the values we need for that:

$V=\frac{1}{3}\pi (16)^2(96)$

This gives us a volume of 25735.93 cubic feet total.

25% of that:

.25 × 25735.93 = 6433.98 ft

Suppose the diameter of a circle is \color{green}{4}4start color green, 4, end color green units. What is its circumference?

Triss [41]

I don’t really understand what this is asking but the formula for circumference is C= πd Remember that diameter (width of the circle) is double the radius (half the width of the circle) and π is about 3.14

Answer:

12.9 square yards

Step-by-step explanation:

The base is an equilateral triangle, so we can assume that the three faces have the same dimensions. Each of those face triangles has an area of ...

A = 1/2bh

A = 1/2(3 yd)(2 yd) = 3 yd²

The base area is computed using the same formula and the given height:

A = 1/2(3 yd)(2.6 yd) = 3.9 yd²

Then the total surface area is that of the base and the three faces:

SA = (3.9 yd²) + 3(3 yd²) = 12.9 yd² . . . total surface area

A vehicle factory manufactures cars. The unit cost (the cost in dollars to make each car) depends on the number of cars made. If

Answer:

The function is missing in the question. The function is $C(x) = 0.8x^2 -544x +97410$

The answer is 4930

Step-by-step explanation:

Unit cost of a car is given as

$C(x) = 0.8x^2 -544x +97410$

Cost will be minimum when

x = -(-544)/ 2 x 0.8

= 340

Therefore, minimum cost for unit car is

$C(x) = 0.8x^2 -544x +97410$

$= 0.8(340)^2 -544(340) +97410$

= 4930
