Answer:
The area of hub cap is 452.16 square centimeters.
Step-by-step explanation:
We are given the following in the question:
Radius of hubcap = 12 cm
A hubcap is of the shape of circle.
Area of hubcap = Area of circle
Area of hubcap =
where r is the radius of the hubcap.
Putting the values, we get,
Thus, the area of hub cap is 452.16 square centimeters.
Answer:
h = 1.4
c = 2.8
Step-by-step explanation:
For each problem, remember the special triangle side ratios then use a proportion. To solve, isolate the variable.
For the triangle with the variable h:
Since two of the angles are 45, this is an isosceles triangle. All isosceles triangles have two equal sides that are not the hypotenuse.
In a right isosceles triangle, the ratio for regular side to hypotenuse is 1 to √2.
h = √2
h ≈ 1.4
For the triangle with the variable c:
The is an equilateral triangle cut in half because the angles are 30 and 60.
The side ratio of altitude to hypotenuse is √3 to 2.
c = 2√2
c ≈ 2.8
