Answer 2

Answer:

The total surface area of the article is 361.1 cm square

Given:

Radius of the cone (r) = 5cm

Height of the cone (h) = 12cm

To Find:

Surface area of the article

Explanation:

Slant height (l) = l² = r² + h²

l = r² + h²

l² = 5² + 12²

l² = 25 + 144

l² = 169

l = 13

Total surface area  =

$= \pi rl + 2 \pi r^{2} \\= \pi * 5 * 13 +2* \pi* 5^{2} \\=361.1 cm^{2}$

The total surface area of the article is 361.1 cm square.

Multiplication:

Mathematicians multiply the numbers in order to calculate the sum of two or more. A fundamental mathematical operation, it is applied frequently in daily life. In order to combine groups of similar sizes, we employ multiplication. An illustration of the fundamental concept of repeated addition of the same integer is multiplication. The product of two or more integers refers to the result of the multiplication, while the factors are the amounts that are being multiplied. It is easier to add the same number repeatedly after it has been multiplied.
