Hello :
the area is : A=<span>πr²
</span> π ≃ 3.14 r : <span>ridus
</span> <span>diameter = 2 r
</span>r = 18/2= 9 ft
A=3.14×9² = 254.34 ft²
Sorry I don’t know the sender maybe someone else can answer
-21.757 because it is right
Answer:
1064 m²
Step-by-step explanation:
The surface area of the prism can be gotten by saying
14 * 14 + 14 * 14 + 14 * 24 =
196 + 196 + 336 =
728 m²
Again, after dealing with the rectangle, we then face the triangle.
Area of triangle is
1/2 * 14 * 24
There are 2 triangles so this makes it
2 * 1/2 * 14 * 24 =
336
The surface area is finally
336 + 728 = 1064 m²
Surface area of the triangular prism has been calculated to be 1064 m²
