Elena L [17]

Answer:

<u>551 square centimeters</u>

Step-by-step explanation:

Finding the radius (r) :

C = 2πr
83.21 = 2 x 3.14 x r
83.21 = 6.28r
r = 83.21/6.28
r = 13.25 cm

Finding the area :

A = πr²
A = 3.14 x (13.25)²
A = 3.14 x 175.5625
A = <u>551 square centimeters</u> (nearest whole number)

<u></u>

The area of this hub cap is about <u>551 square centimeters</u>.

Answer:

Step-by-step explanation:

$Hypotenuse = 8\sqrt{2} \\Adjacent =x\\\alpha =45\\\\Using\: SOHCAHTOA\\Cos \alpha = \frac{Adjacent}{Hypotenuse}\\\\Cos 45 = \frac{x}{8\sqrt{2} } \\\frac{\sqrt{2} }{2} =\frac{x}{8\sqrt{2} }\\ \\Cross \: Multiply\\2x =16\\\frac{2x}{2} =\frac{16}{2} \\\\x =8$
