Cylinder A has a radius of 7 inches and a height of 5 inches. Cylinder B has a volume of 490π. What is the percentage change in volume from cylinder A to cylinder B?

50% decrease

75% increase

150% decrease

100% increase

Percentage change is 100% increase.

Step-by-step explanation:

Step 1: Find volume of cylinder A using equation, V (A) = πr²h, where r = 7 in and h = 5 in

⇒ V (A) = π * 7 * 7 * 5 = 245π

and V (B) = 490π

Step 2: Calculate percentage change from V (A) to V (B)

⇒ % change = [V (B) - V (A) / V (A) ] * 100 = (490π - 245π/245π) * 100

= 245π/245π * 100 = 100% increase
