Circumference=2πr=75
2×3.14×r=75
6.28 r=75
r=75/6.28=11.943=12 inch (nearly)
Answer:
1. $2,950.62
2. $93.75
Step-by-step explanation:
Ann took out a loan of = $12,000
At an interest rate of = 5.65%
Time = 4 years
Formula of compound interest = ![A=P(1+\frac{r}{n})^{nt}](https://tex.z-dn.net/?f=A%3DP%281%2B%5Cfrac%7Br%7D%7Bn%7D%29%5E%7Bnt%7D)
= ![A=12,000(1+\frac{0.0565}{1})^{1\times 4}](https://tex.z-dn.net/?f=A%3D12%2C000%281%2B%5Cfrac%7B0.0565%7D%7B1%7D%29%5E%7B1%5Ctimes%204%7D)
= ![12,000(1.0565)^{4}](https://tex.z-dn.net/?f=12%2C000%281.0565%29%5E%7B4%7D)
= 12,000 × 1.24588514
Interest = Amount - principal amount
= $14,950.62 - 12,000
= $2,950.62
Amount that Dan borrowed = $1,250
rate of interest = 5%
Time = 18 months or 1.5 years
Formula of simple interest = P(1+rt)
= 1250(1+(0.05 × 1.5))
= 1250(1+0.075)
= 1250 × 1.075
= 1343.75
Interest = Amount - principal
I = 1343.75 - 1250
= $93.75
