Answer:
$5,155.7
Step-by-step explanation:
Using the compound interest formula;
Amount = 7600
Time = 7years
Rate = 5.7% = 0.057
Required
Principal
Substitute
A = P(1+r)^n
7600 = P(1+0.057)^7
7600 = P(1.057)^7
7600 = 1.4741P
P = 7600/1.4741
P = 5,155.69
Hence Lilian would need to invest $5,155.7 (to nearest ten dollars)
1041.27
A=πrl+πr2
l=r2+h2
Solving forA
A=πr(r+h2+r2)=π·12·(12+102+122)≈1041.26829
4 would be the answer hopefully
Answer: 731 days
Since 2018 is 2 years away from 2020, that is 730. Add 1 day, that is 731 days.
