The total Surface Area of a right Cone is the sum of the area of its base and the lateral (side) surface.
The formula for the total surface area of a right cone is
Where r is the radius, and l is the slant height
There are 56 different combinations of cards.
This is a combination problem, not a permutation.
Therefore, first we need to find the number of total possibilities.
It would be: 8 x 7 x 6 x 5 x 4
6720
Then, we need to divide those possibilities by the number those 5 cards can be rearranged.
6720 / (5 x 4 x 3 x 2 x 1) = 56

Answer:
54m
Step-by-step explanation:
Area = length x width
Area = 4914
Length = 91
Width = ?
4914 = 91 x w
w = 4914/91
w = 54m
Answer:
5089.4cm³ (rounded to 1 d.p.)
Step-by-step explanation:
Volume of cylinder = × r² × h
Volume of cylinder = × 9² × 20
= 1620
= 5089.4cm³ (rounded to 1 d.p.)
