1004.6025

Step-by-step explanation:

15*30=450

15/2=7.5 (radius)

7.5*7.5=56.25

3.14square*7.5*7.5/2+15*30

3.14square*56.25/2+450

554.6025(3.14square*56.25)+450=

1004.6025

2 x^2 -3x+p

sum of roots = 3/2

let other root be x

3+ x = 3/2

x= 3/2 - 3 = -3/2

product of roots = p/2

3× -3/2 = p/2

-9 = p
