Answer:
Step-by-step explanation:
The smallest angle is opposite to the smallest side.
<u>Use the law of cosines to find the angle opposite to side with the length of 10 cm:</u>
- cos A = (b² + c² - a²)/(2bc)
- cos x = (11² + 13² - 10²)/(2*11*13)
- cos x = 190/286
- cos x = 0.664 (rounded)
- x = arccos (0.664)
- x = 48.4° (rounded)
The answer is 4,615.8 cubic centimeters
The volume of a cylinder is pi*radius^2*height
If pi is 3.14 and you plug in the radius (7cm) and the height (30cm), you get 3.14*7^2*30, which equals 4,615.8 cm cubed
