Answer:

Area of circle = \pi r^2

\pi=3.14 \\ r=28\ \text{in}

\pi r^2=3.14 \times (28 \ \text{in})^2=2461.76 \ \text{in}^2

Since the question ask to round to the nearest tenth, the answer is 2461.8 \ \text{in}^2

Multiply each polynomial <br><br> (x + 5)(x+4)<br><br> teach me step by step
lara [203]

Answer: x^2 + 9x + 20

Step-by-step explanation:

Foil Method: (a + b) (c + d) = ac + ad + bc + bd

Lets say:

a = x

b = 5

c = x

d = 4

Plugging in the numbers: xx + 4x + 5x + 5*4

Combine like terms:

xx = x^2

4x + 5x = 9x

5 * 4 = 20

You're then left with: x^2 + 9x + 20
