What is the surface area of the right cone below?

Mathematics
1 answer:
maksim [4K]3 years ago
6 0

Answer:

SA=54\pi\ units^2

Step-by-step explanation:

we know that

The surface area of the cone is given by the formula

SA=\pi r^{2}+\pi rl

where

r is the radius of the base

l is the slant height

we have

r=3\ units\\l=15\ units

substitute

SA=\pi (3)^{2}+\pi (3)(15)

SA=54\pi\ units^2

I could use some help , i really cant do geometry :(
Gelneren [198K]

Answer:

I am not sure but for

CAE it is 65˚

CBD it is 65˚

Step-by-step explanation:

x+40=3x-10

Move the 3x to the other side by subtracting by 3x on both sides

x-3x+40=3x-3x-10

The equation now looks like this:

-2x+40=-10

Move 40 to the other side by subtracting 40 both sides:

-2x+40-40=-10-40

-2x=-50

Divide by -2 on both sides:

-2x/-2=-50/-2

x=25

Since we found out what x is we can replace x in both CAE and CBD:

For CBD: 25+40 is 65

For CAE: 3(25)-10 is 65

❖ To find the mean, add up all the numbers and divide by the amount of numbers there are. To find the range, subtract the highest number by the  lowest number in the data set.

2. Mean = 35  Range = 78

3. Mean = 43  Range = 58

4. Mean = 63  Range = 73

5. Mean = 61   Range = 56

6. Mean = 55  Range = 83

7. Mean = 61   Range = 53

8. Mean = 60  Range = 75

9. Mean = 50  Range = 76

10. Mean = 50  Range = 81
