Answer:
3 years -> value decreases by 20% 3 times
20% -> value is 80% of the original price
1st year value (after 20% decrease) = S15,500×
= S12,400
2nd year value (after 20% decrease) = S12,400×
= S9,920
3rd year value (after 20% decrease) = S9,920×
= S7,936
36(3.14) = 4/3 x 3.14 x r^3
113.04 = 4.187(r^3)
113.04/4.187 = r^3
26.997 = r^3
3√26.997 = r
r = ~3
Check: 3^3(
)(4/3) = 27(3.14)(4/3) = 113.04
113.04 = 4.187(r^3)
113.04/4.187 = r^3
26.997 = r^3
3√26.997 = r
r = ~3
Check: 3^3(
