The height of the cone is 4 cm (approx).

Step-by-step explanation:

Given,

The radius (r) of the cone = 4.96 cm

Volume (V) = 102 cm³

To find the height (h) of the cone.

Formula

The volume of a cone V = \frac{1}{3}πr²h

Now,

According to the problem,

\frac{1}{3}πr²h = 102

or,  \frac{1}{3}×\frac{22}{7}×(4.96)²h= 102

or, h = \frac{102X7X3}{4.96^{2}X22 }

or, h = 3.95 = 4 (approx)

so,

Height = 4 cm (approx)

A football is thrown by a quarterback to a receiver. The points in the figure show the height of the​ football, in​ feet, above
nevsk [136]

Answer:

Coordinates of the point B will be (14, 3.5).

Step-by-step explanation:

From the graph attached,

Distance between the Quarterback and Receiver = x-coordinate of the point B = 14 yards

Similarly, height of the football from the ground at point B = y-coordinate of the point B = 9 + \frac{12-9}{2}

                   = 9 + 1.5

                   = 10.5 feet

Since, 1 feet = \frac{1}{3} yards

10.5 feet = \frac{10.5}{3}

               = 3.5 yards

Therefore, coordinates of the point B will be (14, 3.5).
