Which equation can be used to find the total surface area of the cylinder with a diameter of 4 inches and height of 15 inches?

• 2πr² + 2πrh = 2π(2)² + 2π(2)(15)

• 2πr² + 2πrh = 2π(4)² + 2π(4)(15)

• πr²h + πrh = π(4)²15 + π(4)(15)

• 2πr²h + 2πrh = 2π(4)²15 + 2π(4)(15)

Which equation can be used to find V, the volume of the cylinder?

• V = (15) π 10

• V = (5) π 100

• V = (10) π 5

• V = (25) π 100
