garik1379 [7]

Answer:

87.92 square inches

Step-by-step explanation:

Surface area for cylinder is given by 2\pi r^2 + 2\pi rh

where r is the radius and h is the height of cylinder.

Given that candle is cylindrical in shape

Thus, Surface area for candle is calculated as given below\\

Surface / area \ for \ candle = 2\pi r^2 + 2\pi rh\\=>Surface / area \ for \ candle = 2*3.14*3^2 + 2*3.14*5\\=>Surface / area \ for \ candle = 2*3.14*3^2 + 2*3.14*5 = 56.52 + 31.4\\=>Surface / area \ for \ candle = 56.52 + 31.4 = 87.92

Thus, total surface area for candle is 87.92 square inches.
