Question

After being filled, a basketball loses 3.2% of its air every day. Considering that the initial volume of the ball was 840 cubic centimetres when it was inflated, what will be the volume in cubic centimetres after 4 days? (Round your answer to one decimal place).

Answer 1

Answer:

volume = 840 cubic cm

(3.2/100)×840= 26.88 per day

after 4 days = 26.88×4=107.5

answer is 107.5

Answer 2

Answer:

Step-by-step explanation:

V(d)= the total amount of air in the ball

V(4)=840(1-0.032)^4 = 840(0.968)^4= 737.53cm^3 which to one decimal place is 737.5cm^3
