Which expression can be used to find the volume of the cylinder in this composite figure? (Answers above on picture)
Thank you!

The expression that can use to find the volume of the cylinder is V = Bh = π(4)²(7) ⇒ A

Step-by-step explanation:

The formula of the volume of a cylinder is V = Bh, where

In the given figure

∵ The composite figure formed from a cylinder and a cone

∵ They have the same base which is a circle

∵ The radius of the circle is 4 cm

∴ The radius of the base of the cylinder is 4 cm

∴ r = 4 cm

→ Find the area of the base B

∵ B = πr²

∴ B = π(4)²

∵ The height of the cylinder is 7 cm

∴ h = 7 cm

→ Substitute the values of B and h in the rule of the volume above

∴ V = π(4)²(7)

∴ V = BH = π(4)²(7)

∴ The expression that can use to find the volume of the cylinder is

   V = Bh = π(4)²(7)

  about 5.6 days

step-by-step explanation:

we can fill the given information into the decay equation and solve for the value of t at which half the sample remains.

the half-life is about 5.6 days.
