The amount in the account is now 10 118 dollars for 6 years that earned 8% annual interest.
=> 10 118 dollars / 6 years = 1686.33 dollars per year.
=> <span>1686.33 dollars * .08 = 134.91 dollars is the interests per year
</span>=> <span>1686.33 dollars - 134.91 dollars = 1551.42 dollars per year

So 161 divide 7 equals 23 so therefor he types 23 words per minutes. 23 times 20 equals 460. I think he can type 460 words in 20 minutes.
Step-by-step explanation:
step 1. the area of a circle is A. A = (pi)r^2.
step 2. if the diameter is 8 cm then the radius is 4 cm.
step 3. A = (pi)4^2
step 4. A = 16(pi) = 50.24 cm.
