Question

Please Help! Extra points and braniest will be given.

Answer 1

Answer:

A≈297.33

Step-by-step explanation:

A=πrl+πr2

l=r2+h2

Solving forA

A=πr(r+h2+r2)=π·5·(5+132+52)≈297.32643

Answer 2

Answer:

282.6

Step-by-step explanation:

The formula for finding the surface area of a cone is

→ ( π × r × l ) + ( π × r² )

Where "r" is the radius and "l" is the slant height

The reason this formula has 2 parts to it is because the ( π × r × l ) is to find the surface area of the curved part and not the area of the underside so that's where  ( π × r² ) to find the area of the circle underneath so lets start substituting in the values,

( π × r × l ) + ( π × r² )

→ Put in the values

( π × 5 × 13 ) + ( π × 5² )

→ Simplify

65π + 25π

→ In the question it says put 3.14 for π

( 65 × 3.14 ) + ( 25 × 3.14 )
