Answer:
a) 204.20 square centimeters
b) 282.74 square centimeters
c) 314.16 cubic centimeters
Step-by-step explanation:
a)
The curved surface area of a cone is given by:
Curved Surface Area of Cone = 
Where r is the radius (given as 5) and l is the slant height, the hypotenuse of the right triangle formed (right side) with 5 as base and 12 as height.
We can find the slant height by using pythagorean theorem on the triangle:
12^2 + 5 ^2 = l^2
144 + 25 = l^2
169 = l^2
l = 13
Now,
Curved Surface Area of Cone =
square centimeters
b)
Total surface area is curved surface area PLUS the area of the bottom, which is a circle with area 
So the bottom has an area of 
Hence, The total surface area = 204.20 + 78.54 = 282.74 square centimeters
c)
The volume of cone is given by 
Where radius is 5 and height is 12, so we have:
Volume of Cone =
cubic centimeters

Answer:
$450
Step-by-step explanation:
x/3000 = 5/100 (Cross multiply)
100x = 3000(5)
100x = 15000
100x/100 = 15000/100
x = 150
150(3) = 450

Just know that:
n! = n(n-1)!
= n(n-1)(n-2)!
= n(n-1)(n-2)(n-3)!
= ...
