lilavasa [31]

Answer:

$P(x)=(x+9)(x^2-7x+52)+3$

Step-by-step explanation:

We are given that

$P(x)=x^3+2x^2-11x+471$

$d(x)=x+9$

We have to find the value of Q(x) and Remainder R(x).

Quotient, $Q(x)=x^2-7x+52$

Remainder, $R(x)=3$

We know that

$Dividend=Divisor\times Quotient+Remainder$

$P(x)=(x+9)(x^2-7x+52)+3$

amid [387]

Answer:

Step-by-step explanation:

Area of circle = π r²

r = 30

30² = 900

π = 3.14 or ≈ 3

A ≈ 900 × 3

A ≈ 2700

so C at 2830 is closest to the answer
