Answer:
b = 5/12
Step-by-step explanation:
1. Cross multiply -> 1 x 5 = 5 and 3b x 4 = 12 b
2. Simplify -> 5 = 12b and switch sides so it's easier: 12b = 5
3. Divide both sides by 12 -> 12b ÷ 12 = b and 5 ÷ 12 = 5/12
4. So, the answer is b = 5/12

Given:
The sides of the right triangular base measures 9 cm, 12 cm and 15 cm.
The height of the prism is 20 cm.
To find:
The surface area of a triangular prism.
Solution:
We know that, the area of a triangular prism is
Where, P is the perimeter of the triangular base and h is the height of the prism.
The sides of the right triangular base measures 9 cm, 12 cm and 15 cm. So, the perimeter of the right triangular base is
Now, the area of the triangular prism is
Therefore, the surface area of a triangular prism is 720 square centimetres.
Radius after dilation = 4 * 1/2 = 2 in
Now, C = 2πr
C = 2π(2)
C = 4π
Or C = 4 * 3.14 = 12.56
In short, Your Answer would be 4π or 12.56 in
Hope this helps!
