Find the surface area of the composite solid. Leave your answer in terms of pi

Step-by-step explanation:

total surface area = lateral area of cone + lateral area of cylinder + area of base of cylinder:

cone: πrL = π(5cm)(13cm) = 65πcm²

cylinder: 2πrh = 2π(5cm)(12cm) = 120πcm²

base: πr² = π(5cm)² = 25πcm²

total surface area = 65πcm² + 120πcm² + 25πcm² = 210πcm²

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.
