Step-by-step explanation:
<u>Surface Areas </u>
Is the sum of all the lateral areas of a given solid. We need to compute the total surface area of the given prism. It has 5 sides, two of them are equal (top and bottom areas) and the rest are rectangles.
Computing the top and bottom areas. They form a right triangle whose legs are 4.5 mm and 6 mm. The area of both triangles is
The front area is a rectangle of dimensions 7.7 mm and 9 mm, thus
The back left area is another rectangle of 4.5 mm by 9 mm
Finally, the back right area is a rectangle of 6 mm by 9 mm
Thus, the total surface area of the prism is
Answer:
Concept: Area
- We are given area hence 78.5 square meters
- We want the radius so we isolate
- Isolate for r to get r= 4.99 or 5 square units approximately
1) y= -5
2) m = -1
3) k = 3
4) y = -5
