The correct answer is - B. 5.24 lb.

Explanation:

Given is a bowling ball, so it is a sphere.

The radius is given as = 5 inches

Volume of the sphere = \frac{4}{3} \pi r^{3}

Putting r=5 and pi = 3.142 in the above formula, we get

volume = 523.66 cubic inches

Also given is - one cubic inch weighs 1/100th of a pound

So, 523.66 cubic inches will weigh = \frac{523.66}{100}=5.2366

Hence rounding this off we get the weight of the bowling ball as 5.24 lb.

blondinia [14]

Answer:

<h2>The answer is option C</h2>

Step-by-step explanation:

To find an equation of a line in point slope form when given the slope and a point we use the formula

y -  y_1 = m(x -  x_1)

where

m is the slope

( x1 , y1) is the point

From the question the point is (1,2) and the slope is 6

The equation of the line in point slope form is

<h2>y - 2 = 6( x - 1)</h2>
