Answer:
- 2s: 45,239 cm²/s
- 5s: 113,097 cm²/s
- 6s: 135,717 cm²/s
Step-by-step explanation:
The radius is a function of time:
r(t) = 60t . . . . . radius in cm; time in s
Then the area of the circle is ...
A = πr² = π(60t)² = 3600πt²
The rate of change of area is the derivative of this:
A' = 2·3600πt = 7200πt
The rates of change of interest are ...
after 2s: 45,239 cm²/s
after 5s: 113,097 cm²/s
after 6s: 135,717 cm²/s
The correct answer is option c
Answer:
3/12
Step-by-step explanation:
first you find the l. c. m of the denominators.you will find the l. c. m as 36.you will then multiply 36 by both fractions
