Answer: The answer is true :)
Answer:
144
Step-by-step explanation:
V=PIr^2h
PI=3
V=3r^2h
r=2 h=12
V=3(2^2)12
V=3(4)12
V=12(12)
V=144in^3

<h3>Solution</h3>
Use the equation for total surface area of cylinder:
- S = 2πr² + 2πrh or S = 2πr(r + h)
Since we have r = h and the value of S is known, let's solve this equation:
- 2πr(r + h) = 300
- 2πr(r + r) = 300
- 2πr(2r) = 300
- 4πr² = 300
- πr² = 75
- 3.14r² = 75
- r² = 75/3.14
- r² = 23.89 (rounded)
- r = √23.89
- r = 4.89 cm (rounded)
