I dont think we can see the whole problems
like half of it is cut off
can you please fix it ??
thanks :3
Answer:
a) Surface area = 616 cm²
b) Volume = V = 1083 cm³
Step-by-step explanation:
Surface area and volume of a regular triangular pyramid that has a base edge of 16 cm and a slant height of 15 cm
a) Formula for surface area = Base area × 1/2(perimeter × slant height)
Base area = Base edge²
=( 16 cm)² = 256 cm²
Perimeter = Base edge × 3
= 16 cm × 3 = 48 cm
Hence:
Surface Area = 256 cm² + 1/2(48 × 15)
= 256 cm² + 360 cm²
= 616 cm²
b) Volume = 1/3 × Base area × Height
1082.758616785cm³
Approximately = 1083 cm³

Answer:
Step-by-step explanation:
We want to simplify the radical expression:
We write √6 as √(2*3).
This implies that:
We now split the radical for √(2*3) to get:
We obtain a perfect square at the far right.
This simplifies to
This gives us:
and finally, we have:
