Answer:
Step-by-step explanation:
surface area of cylinder=2rh
or,234=2*22/7*9*h
or,234*22/7=396/7*h
or,5148/7=396/7*h
or,36036=2772h
or,36036/2772=h
h=13
now,
volume=r^2h
=22/7*(9)^2*13
=3309.4285
Answer: (a)
(b) A = $1680.67
(c) t = 9.99 years
(d) A = $1689.85
<u>Step-by-step explanation:</u>
where
- A is the amount accrued (balance)
- P is the principal (original/initial amount)
- r is the interest rate (convert to a decimal)
- n is the number of times compounded per year
- t is the number of years
a) Given: P = 900, r = 7% = 0.07, n = quarterly = 4
b) Given: P = 900, r = 7% = 0.07, n = quarterly = 4, t = 9
A = 1680.67
c) Given: A = 1800, P = 900, r = 7% = 0.07, n = quarterly = 4
d)
Given: P = 900, r = 7% = 0.07, t = 9
