The total surface area of the cone is 542.592 square mm
<h3>Total surface area of a cone</h3>
The formula for calculating the total surface area of a cone is expressed as:
TSA = πr(r + l)
where
r is the radius of the cone
l is the slant of the cone
Given the following parameter
l = 13.6mm
r = 8mm
Substitute
TSA = π(8)(8+13.6)
TSA = 3.14(8)(21.6)
TSA = 542.592 square mm
Hence the total surface area of the cone is 542.592 square mm

Answer:
4740
Step-by-step explanation:
Unless there are options, then I would need to know that
Answer:
C
Step-by-step explanation:
because acute angles have to be less than 90 degrees so therefore it's C.
4/5 is the same as 80% or .80, so it's larger than 76% and .77
