To find the surface area of a cylinder, use the formula SA = 2(pi)(radius^2) + 2(pi)(radius)(height).
So now, plug in what you know.
SA = 2(3.14)(5^2) + 2(3.14)(5)(9)
SA = (6.28)(25) + (6.28)(45)
SA = 157 + 282.6
SA = 439.6 square cm
439.6 square cm is your surface area
Answer:
= -25x-19/10
Step-by-step explanation:
Given:
The figure of triangle ABC.
The area of the triangle ABC is D.

To find:
The value of m and n in the given expression.
Solution:
Let h be the height of the triangle ABC.
Area of a triangle is:

Where, b is the base and h is the height of the triangle.

The area of the triangle ABC is D.


...(i)
In a right angle triangle,


[Using (i)]
...(ii)
We have,
...(iii)
On comparing (ii) and (iii), we get


Therefore, the required values are
.
5 (7 + 23)
(Use distributive property to solve)
1. 5*7 + 5*23
2. 35 + 115
3. 150
