What is the surface area of the square pyramid? (100 POINTS BTW) (:
A:60 cm2

B:132 cm2

C:228 cm2

D:288 cm2

Step-by-step explanation:

A square pyramid has 5 faces.

Surface area of the base which is a square= 6×6 cm²

= 36cm²

There are 4 triangles.

Area of one right angle triangle =

Area of the 4 triangles = 24×4cm ²

= 96cm²

Surface area of the square pyramid= 36+96cm²

= 132cm²

Option B

question is incomplete.

answer:

step-by-step explanation:

here, the total dishes = 10

dishes having meat = 3 ( chicken, meatloaf and hamburger )

thus, the probability of having meat on the chosen dishes = number of dishes having meat / total dishes

=

therefore, the probability of not having meat = 1- the probability of having meat on the chosen dishes

=

=

=

⇒ option b is correct.
