Answer:
725,000
Step-by-step explanation:
The number to the right of 5 is 3, it's lower than five so your thousand is going to stay the same number. If your hundreds place is greater than 5, then it would be rounded to 726,000.
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
Area equals pi r squared, and if the diameter is 8 feet, then the radius would be 4 feet. 4 squared is 16, so if you’re answering in terms of pi, it’s 16 pi but if you’re answering in terms of feet it’s about 50.27 Feet
