Area of a circle = (3.14) * r^2
d = 7
r = 3.5

a = (3.14) * 3.5^2
a = (3.14) * 12.25
a = 38.47

a rectangular prism has a volume of 4,212 cubic yards, width 2 yards, and length 27 yards find it’s height in yards
weqwewe [10]

Answer:

height = 78 yd

Step-by-step explanation:

<u>Formula</u>

Volume of a rectangular prism = width × length × height

Given:

  • volume = 4,212 yd³
  • width = 2 yd
  • length = 27 yd

Substituting given values into the formula and solving for height:

⇒ 4212 = 2 × 27 × height

⇒ 4212 = 54 × height

⇒ height = 4212 ÷ 54

⇒ height = 78 yd
