Answer:
Step-by-step explanation:
The surface area of a cone is given by the following formula:
(1)
Where:
is the surface area
is the radius of the base of the cone (assuming it is a circumference)
is the slant height
Rewriting (1):
(2)
Isolating :
This is the slant height of the cone in termsof
Answer:
Step-by-step explanation:
We begin with the differential equation
Firstly, we need to get the and as well as the and on the same sides as each other
To do this, we can multiply each side by and divide each side by
Doing this will give us the following differential
Now, we can integrate each side
Now, we need to solve for y
The key to solving this problem is drawing a rectangle outside the figure and subtracting the reas of the triangles formed from the are of the rectangle. You can look at the attched image if you want a visual.So first let's find the area of the rectangle, the length is 11 and the width is 5 so the area is 55. Now let's find the area of the trinagles. Triangle 1 has sides of 4 and 3 so the area is 6. Triangle 2 has sides of 5 and 5 so the area is 25/2. Triangle 3 has sides of 2 and 5 so the area is 5. Now let's add the area of the triangles up to get 47/2. Now let's subtract 47/2 from 55 to get the area of the figure which is *drumroll*...63/2. that's all.
