Answer:
D
Explanation:
The volume of a single coin is indeed:
Volume of a single coin = π × (radius)² × height
= 3.14 × (1.4 in)² × 0.0625 in
= 0.38465 in³ (rounded to the nearest hundredth)
Therefore, the total volume of 230 coins can be found by multiplying the volume of a single coin by the number of coins:
Total volume of 230 coins = 0.38465 in³/coin × 230 coins
= 88.47 in³ (rounded to the nearest hundredth, unrounded its 88.4695)
Hence, the answer is (D) 88.47 in³.
