Its is 9 cm. I know because the 13 cm side isn't equivalent to the 13 cm side so if you measure it like i did you will get the answer 9cm.
Answer:
Volume of cone = 418.67 cm³ (Approx.)
Step-by-step explanation:
Given:
Radius of cone = 5 cm
Height of cone = 16 cm
Find:
Volume of cone
Computation:
Volume of cone = [1/3][π][r²][h]
Volume of cone = [1/3][3.14][5²][16]
Volume of cone = [1/3][3.14][25][16]
Volume of cone = [1/3][3.14][400]
Volume of cone = [1/3][1,256]
Volume of cone = 418.67 cm³ (Approx.)
