Answer:
Area of circle = 465.82 cm²
Step-by-step explanation:
Given the following data;
Circumference of the hub cap = 76.49 cm
Pie, π = 3.14
To find the area of the hub cap;
First of all, we would determine the radius of the hub cap.
Mathematically, circumfeence of a circle is equal to;
C = 2πr
Where:
C is the circumference of a circle.
r is the radius of a circle.
C = 2πr
76.49 = 2 * 3.14 * r
76.49 = 6.28r
Radius, r = 76.49/6.28
Radius, r = 12.18 cm
Next, we find the area of the hub cap;
Area of circle = πr²
Area of circle = 3.14 * 12.18²
Area of circle = 3.14 * 148.35
Area of circle = 465.82 cm²
However, if the circumference of the hub cap were smaller, the area of the hub cap would also be smaller. Thus, the circumference of a hub cap is directly proportional to the area of a hub cap.

For 27,the temp and time increase
Answer: 12=7−3x+5x
Step 1: Simplify both sides of the equation.
12=7−3x+5x
12=7+−3x+5x
12=(−3x+5x)+(7)(Combine Like Terms)
12=2x+7
12=2x+7
Step 2: Flip the equation.
2x+7=12
Step 3: Subtract 7 from both sides.
2x+7−7=12−7
2x=5
Step 4: Divide both sides by 2.
