Number of ways of selecting committee with atleast 2 girls :

We either have :

(2 girls 1 boy) or (3girls 0 boy)

nCr = n! ÷ (n-r)!r!

4C2 = 4! ÷ 2!2! = 6

6C1 = 6! ÷ 5!1! = 6

4C3 = 4! ÷ 1!3! = 4

6C0 = 6! ÷ 6!0! = 1

BabaBlast [244]
Circumference = πD
πD = 56.52
D = 17.99 in

Area of the pizza = π (17.99 ÷ 2)²  = 254.19 in²

Area of the pizza eaten = 254.19 ÷ 4 = 63.55 in²

Area of the pizza remain = 254.19 - 63.55 = 190.64 in²

Answer: 190.64 in²
