To find the total surface area of a closed cylinder, you can use the formula: Total Surface Area = 2πr(h + r), where r is the radius and h is the height. Plugging in your values (r = 3 cm and h = 7 cm), the total surface area is approximately 188.5 cm².
Eureka! Now that you’ve calculated it, think about this: in real-world applications, knowing the surface area is crucial! For example, if you’re designing a can or any cylindrical container, this knowledge helps you determine how much material you’d need or even how much paint to cover it. Pretty handy, right?
