Answer: [C]: 50.2 m<span>²
__________________________

Since: Area of a circle: A = </span> $\pi$ * r² ';

And: A = $\pi$ = 3.14 * 4² = 3.14 * 16 ;

We know that the area will be a bit more that ( 3 m * 16 m = 48 m²) ;

And, Answer choice: [C]: 50.2 m² ; is the closest value.

Find 3 consecutive odd numbers where the product of the smaller two numbers is 22 less than the square of the largest number.

Anton [14]

Answer:

1,3,5

Step-by-step explanation:

1) your 3 consecutive odd integers would be x,x+2,x+4

The smaller two integers are:x and x+2

(X)(x+2)=(x+4)^2-22

Distribute

X^2+2x=x^2+16+8x-22

X^2 cancels each other out and 16-22=-6
