During play, a ball with a diameter of 3.00 inches splits exactly in half. What is the volume of each portion of the ball?
Luba_88 [7]

Answer:

7.05 in^3

Step-by-step explanation:

V = 4/3(pi)r^3 , r = 3/2 = 1.5

V = (4/3)(3.14)(1.5^3)

= 14.10

Now divide by 2 for 1/2 of the ball.

V/2 = 14.10 = 7.05

= 7.05 in^3

How much of a radioactive kind of calcium will be left after 10 days if the half-life is 5 days
Sophie [7]

Answer: 16 g

Step-by-step explanation:

We can solve this with the Radioactive Half Life Formula:

A=A_{o}.2^{\frac{-t}{h}}    

Where:

A is the final amount of radioactive calcium

A_{o}=64 g is the initial amount of radioactive calcium

t=10 days is the time elapsed

h=5 days is the half life of radioactive calcium

Solving with the given data:

A=(64 g)2^{\frac{-10 days}{5 days}}    

A=16 g  This is the amount of radioactive calcium left
