Question

The Candle Factory is producing a new candle. It has a radius of 3 inches and a height of 5 inches. What is the surface area of the candle? Use 3.14 for Pi. Round to the nearest whole square inch.

A cylinder with a radius of 3 inches and height of 5 inches.


Recall the formula S A = 2 pi r squared + 2 pi r h.
48 square inches
151 square inches
251 square inches
414 square inches

Answer 1

Answer: 151sq

Explanation:

You may use the formula for a cylinder's surface area to determine the candle's surface area:

SA = 2πr^2 + 2πrh

Given:

Radius (r) = 3 inches

Height (h) = 5 inches

Pi (π) = 3.14 (approximately)

Now, enter the values into the formula to get:

SA = 2 * 3.14 * 3^2 + 2 * 3.14 * 3 * 5

SA = 2 * 3.14 * 9 + 2 * 3.14 * 3 * 5

SA = 56.52 + 94.2

SA ≈ 150.72 square inches

The candle has a surface area of around 151 square inches.
