To solve this problem you must follow the proccedure below:
a<span>. Find the perimeter and area of the cracker remaining:
The perimeter of a quarter circle is:
P=(</span>πr/2)+2r P=(πx3 cm/2)+2(3 cm) P=10.71 cm
The perimeter of <span>the cracker remaining is: </span><span> Pt=3 cm+6 cm+3 cm+10.71 cm Pt=22.71 cm
The area of a quarter circle is:
A=</span>πr²/4 A=π(3 cm)²/4 A=7.06 cm² <span> The area of</span><span>of the cracker remaining is: </span><span> At=Area of a square-Area of quarter circle At=L</span>²-(πr²/4) At=(6 cm)²-(π(3 cm)²/4) At=28.93 cm² <span> b. About how many bites can you get from the entire cracker?</span>
