Answer:
1. The area of the circle is 132.67 square centimeters
2. The area of the rectangle is 60 square centimeters
3. The area of the shaded region is 72.67 square centimeters
Step-by-step explanation:
* Lets explain how to solve the problem
- A rectangle is inscribed in a circle, that means the vertices of the
rectangle lie on the circumference of the circle
∴ The diagonal of the rectangle = the diameter of the circle
- From the attached figure
∵ The diameter of the circle = 13 cm
∵ The radius of the circle is half the diameter
∴ The radius of the circle = 1/2 (13) = 6.5 cm
- The area of the circle = πr²
∵ π = 3.14
∴ The area of the circle = 3.14 × (6.5)² = 132.67 cm²
1. The area of the circle is 132.67 square centimeters
- The area of any rectangle = length × width
∵ The length of the rectangle is 12 cm
∵ The width of the rectangle is 5 cm
∴ The area of the rectangle = 12 × 5 = 60 cm²
2. The area of the rectangle is 60 square centimeters
- The area of the shaded region is the difference between the
area of the circle and the area of the rectangle
∵ The area of the circle = 132.67 cm²
∵ The area of the rectangle = 60 cm²
∵ The area of the shaded region = area of circle - area of rectangle
∴ The area of the shaded region = 132.67 - 60 = 72.67 cm²
3. The area of the shaded region is 72.67 square centimeters
3. AABC is made of (chords in, tangents to) OX.
4. ZDEF is an (intercepted arc, inscribed angle) of OX.
Answer:
1 . EF is a secant of OX
2. DF is a chord of OX.
3. AABC is made of tangents to OX
4. ∠DEF is an inscribed angle of OX.
Step-by-step explanation:
Secant is line which intersects a circle from two distant points. Locus is a set of points which is same distance from the center of a circle. Chord is a straight line whose end points lie on circular arc of a circle. Tangent is a line which touches the circle at one point only.

The distance from point F to point H is 15 units. Option C is correct.
In order to get the distance from point F to point H, we will use the distance formula as shown:
Given the coordinate points F(0,0) and H(9, 12)
Hence the distance from point F to point H is 15 units. Option C is correct.

Answer:
Quan runs a maximum of 5.3 miles and a minimum of 4.7 miles every day.
Step-by-step explanation:
Let x= the actual measurement.
|actual − ideal|≤ tolerance
Use an absolute value inequality to express this situation.
|x−5|≤0.3
Rewrite as a compound inequality.
−0.3≤x−5≤0.3
Solve the inequality.
4.7≤x≤5.3
Answer the question. Quan runs a maximum of 5.3 miles and a minimum of 4.7 miles every day.
