Suppose Mahkah makes a Native American lunch in a pot that is shaped like a right cylinder. If

Harman [31]

The pot can hold 5.23 quarts

Step-by-step explanation:

Step 1: Find the volume of the right cylinder shaped pot.

Diameter of the pot = 8 in

⇒ Radius = 4 in

Height = 6 in

⇒ Volume of the pot = πr²h = 3.14 × 4² × 6

= 301.44 in³

Step 2: Convert inches to quarts.

1 in³ = 0.017316 liquid quarts

⇒ 301.44 in³ = 301.44 × 0.017316 = 5.23 quarts
