Make each an improper fraction. Turn them into improper fractions by multiplying the whole number by the denomintor then adding the numerator and putting it over the original denominator. Then subbtract by multipying the second fraction by 4/4 and then subtract and simplify if possible. Hope this helped!

Answer:

506.7 cm²

Step-by-step explanation:

The amount of cardboard needed would be the surface area of the cone,

S= pi(r)(l+r) where r is the radius and l is the slant height.

You can find l using the Pythagorean theorem. l²=r²+h² which is l²=6²+20² and you get l = √436.

Plug r and l into the equation: S = 6pi(√436 + 6) = 506.7 cm²

Let me know if you have any questions about my steps!
