Daniel is blowing up a beach ball in the shape of a sphere. The package says that the ball has a diameter of 9 inches. Which measurement is closest to the volume of the beach ball when it is completely filled with air? A. 84.8 cubic inches

B. 381.7 cubic inches

C. 972 cubic inches

D. 3,053.6 cubic inches

B. 381.7

Step-by-step explanation:

because the diameter is 9 we know the radius is 4.5 (radius is half of the diameter)

the formula for volume: V= 4/3πr^3

V=4/3•π•4.5^3

that equals approx. 381.7

b.) 160 miles on a 5 gallons car

step-by-step explanation:

240/10=24 miles/gallon

160/5=32 miles/gallon

30/1=30 miles/gallon

168/6= 28 miles/gallon

32 miles/gallon is the most amount, so this is the best.

(w – 2.5)(w + 2.5)

(–4v – 9)(–4v + 9)
