The supreme choice pizza at Pizza Paradise contains 22 different meats and 33 different vegetables. The customer can select any
mash [69]

Answer:

1680 possible pizzas

Step-by-step explanation:

Pizza contains 2 different meat and 3 different vegetables.

If there are 5 meats and 8 vegetables, the customer can select any one of 3 types of crust.

Total number of ways to select meat = 5C2

nCr = n! /(n-r)! r!

5C2 = 5! / (5-2)!2!

= 5! / 3!2!

= 10

Total number of ways to select vegetables = 8C3

= 8!/(8-3)!3!

= 8! / 5!3!

= 56

Total number of pizza choice that can be made = 3 * 5C2 * 8C3

= 3*10*56

= 1680 possible pizza

Answer:

24 cm

Step-by-step explanation:

Divide by 2 on both sides:

150.72 = 2\pi r

/2           /2

75.36=\pi r

Divide by pi on both sides:

75.36=\pi r

/pi        /pi

24 = r

Therefore, the radius is 24 cm.
