Triangle PQR and STR are shown. Which of the following does Not justify PQR ~STR ?
1 answer:
The equation that does not justify the similarities of both triangles is:
Similar triangles may or may not have congruent sides.
The triangles are given as:
- Triangle PQR
- Triangle STR
The above means that, the following sides are similar
- Line segments PQ and ST
- Line segments QR and TR
- Line segments PR and SR
So, the equation that does not justify the similarities of both triangles is:

Answer:
The surface area of the cone is 126π cm².
Step-by-step explanation:
The surface area of a cone can be found using this formula:
- where r = radius and l = slant height
In this problem, we are told that the cone has a radius of 9 cm and a slant height of 5 cm.
Substitute these values into the formula for the surface area of a cone.
The surface area of the right cone is 126 π cm².
