Answer:
The area of this hub cap is about 470.46 square centimeters.
Step-by-step explanation:
Circumference (C) = 2π radius
Replacing with the values given:
76.87 = 2 (3.14) r
Solving for r (radius)
76.87/ (2x 3.14) =r
r = 12.24 cm
To find the Area:
Area of a circle = π r^2
A = 3.14 (12.24)^2
A = 470.46 cm2
If the circumference of the hub is smaller, the area is also smaller because it means that the radius of the circle decreases.

9.5x = (52)(3.25)
9.5x = 169
x = 17.8

Altogether Katrina and her seven friends equal eight. Eight divided by four is two cookies. The answer is 2.
40x6=240 (normal time)
6.5x9=58.5 (overtime)
8x12=96 (holiday)
240+58.5+96=394.5
