What is the weight of a bowling ball with a 5 in. radius if we know that one cubic inch weighs 1/100th of a pound? a. 6.54 lb. b. 5.24 lb. c. 9.86 lb. d. 10.99 lb

The weight of a bowling ball is 5.24 pounds.

Option (B) is correct.

Step-by-step explanation:

Formula

Where r is the radius of a sphere.

As given

The radius of the ball is 5 in.

As the shape of the ball is spherical .

Thus

Thus

Volume of a ball = 523.8 in³ (Approx)

As

Thus

Convert  523.8 in³ into pounds.

Therefore the weight of a bowling ball is 5.24 pounds.

Therefore Option (B) is correct.

y < -3

step-by-step explanation:

-3y - 2 > 7

-3y -2 + 2 > 7+2

-3y > 9

-3y/-3 < 9/-3   (change the inequality sign when multiplying or dividing by a negative number)

y < -3
