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:
x = 2
Step-by-step explanation:
The product of secant lengths to the near and far circle intercepts is the same for both secants:
3 · (3+5) = 4 · (4+x)
24 = 4(4 +x) . . . . simplify
6 = 4 +x . . . . . . . .divide by 4
2 = x . . . . . . . . . subtract 4

Answer:
−3+(−2)(5)+7
=−6
Step-by-step explanation:
Multiply and divide left to right (-2) (5) : 10
Apply rule -a x b = a x b
(-2)(5)= -2 x 5 = -10
= -3 - 10 +7
Add and subtract left to right
-3-10+7
-3 - 10 = 13
= -13 + 7
-13 + 7 = -6
= -6

if x is the bigger num and y is the smaller
x + y = 91
x - 3y = 7.7
multiply by -1
x+y = 91
-x + 3y = -7.7
add the equations
4y = 91 - 7.7
4y = 83.3
y = 20.825
then x+y = 91 use to find x
x+20.825 = 91
x = 70.175
the two numbers are 70.175 and 20.825
