Given:
In the given cone,
Radius of the cone = 7.2 m
Slant height of the cone = 17 m
To find:
The surface area of the cone.
Solution:
The surface area of a cone is:
Where, r is the radius of the cone and l is the slant height of the cone.
Putting 
in the above formula, we get
Therefore, the surface area of the given cone is 547.11 square m.
Answer:
l = 10 feet, m = 30 feet and n = 25 feet
Step-by-step explanation:
The attached figure shows a triangle in which three sides as as follows :
, m and 
Perimeter of triangle is 65 feet.
Perimeter = sum of all sides
put the value of n
Now put the value of l
⇒ 
And
Hence, l = 10 feet, m = 30 feet and n = 25 feet.
Answer:
w=7
Step-by-step explanation:
It would be (3y+1)(y+5), because the factors of 3 are 1 and 3, and factors of 5 are 1 and 5, 3*5=15,1*1=1, 15 and 1 make a sum of 16
