Answer:
B) each piece has 1/8 of 3 feet ribbon
Step-by-step explanation:
Given,
The total length of the ribbon = 3 feet,
Total number of pieces of the ribbon = 8,
If each piece has the same length,
So, the length of each piece
= 1/8 of 3 feet
Hence, OPTION B is correct.
4x^2+4x-1
O f(x) = x(x – b) 3
we know that
The formula of the surface area of the cone is equal to
where
SA is the surface area
r is the radius of the cone
l is the slant height
in this problem we have
Solve the formula for l
substitute the values
therefore
<u>the answer is</u>
The slant height is
