Step-by-step explanation:
80 x (7 / 10) = 56
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:
88
Step-by-step explanation:
(17 * 11 = 187) + (9 * -11 = -99)
187 - 99 = 88
Answer:
Step-by-step explanation:
(-5) * (-3) * (-3) = -5 * -3 * -3 = 15 * -3 = -45
Answer:
9
Step-by-step explanation:
perfect square sholud be 
so (w+3)*(w+3) is perfect square and extention of it is =>w*w+6w+9
