Answer:

Step-by-step explanation:
<u>Volume of a Cone</u>
The volume of a right circular cone with height h and a base radius r is:

The height of the given cone is h=4.1 cm and its diameter is d=14.8 cm. Since the radius is half the diameter, r=7.4 cm.
Calculate the volume:




If it costs 650 per kg then 500g will cost half of that as 500g is half of a kg so the answer is 650/2 = 325
The solution to the system of equations is (x, y) = (10, 14), where x is the number of 3-point questions and y is the number of 5-point questions. The appropriate choice is ...
The test contains 10 three-point questions and 14 five-point questions. (2nd selection)
KE = 1/2(m * v^2)
KE = 1/2(1350 * 12^2)
KE = 1/2(1350 * 144)
KE = 1/2(194,400)
KE = 97,200 Joules
