Answer:
288π or 904.78
Step-by-step explanation:
We know that the diameter of this beach ball is 12 inches and we want to determine how much air it can hold using the formula for the volume of a sphere which is
× π × r³ where 'r' is the radius. In the question we are given the diameter not the radius but we can half the diameter to find the radius so 12 ÷ 2 = 6. The radius of the beach ball is 6 inches so let's work out how much air it can hold.
Volume =
× π × r³
→ Let's substitute in the values
Volume =
× π × 6³
→ Simplify
Volume =
× π × 216
→ Simplify further
Volume = 288π or 904.78
Answer:
Step-by-step explanation:
20 increased to 22
20/22= 10%
10% of 20.00 is $2.00
2+20 = 22
38(m - 29) = 434...distribute thru the parenthesis
38m - 1102 = 434...add 1102 to both sides
38m = 434 + 1102
38m = 1536....divide both sides by 38
m = 1536/38
m = 768/19 or 40 8/19
