1. If the radius of a circle is 36 cm, the diameter would be 72 cm. True or False?

Explanation

The statement is true because the diameter of a circle is always twice the length of its radius. So if the radius is 36 cm, then the diameter would be 72 cm.

2. The diameter of a circle is twice the radius of a circle. True or False?

Explanation

The diameter of a circle is a straight line passing through the center and connecting two points on the circumference. It is always twice the length of the radius, which is the distance from the center to any point on the circumference. Therefore, the statement that the diameter of a circle is twice the radius is true.

3. The radius of a circle is the distance around the circleTrue or False?

Explanation

The statement "The radius of a circle is the distance around the circle" is false. The radius of a circle is actually the distance from the center of the circle to any point on its circumference. The circumference, on the other hand, is the distance around the circle. So, the radius and the circumference are two different measurements in a circle.

5. If the diameter of a circle is 12 inches, the radius would be 24 inches. True or False?

Explanation

The statement is false. The radius of a circle is always half of its diameter. Therefore, if the diameter of a circle is 12 inches, the radius would be 6 inches, not 24 inches.

6. Find the Circumference of the circle. Use 3.14 for

Explanation

The circumference of a circle can be found using the formula C = 2πr, where π is approximately 3.14 and r is the radius of the circle. In this case, the circumference is given as 50.24 mi. By rearranging the formula, we can solve for the radius: r = C / (2π). Plugging in the given circumference, we get r = 50.24 / (2 * 3.14) = 8 mi. Therefore, the correct answer is C = 50.24 mi.

7. Find the circumference of the circle. Use 3.14 for   radius = 9.5 inches

Explanation

The circumference of a circle can be found using the formula C = 2πr, where r is the radius of the circle. In this case, the radius is given as 9.5 inches. Plugging this value into the formula, we get C = 2 * 3.14 * 9.5 = 59.66 inches. Therefore, the correct answer is C = 59.66 inches.

Submit
8. Find the Area of the circle. Use 3.14 for  

Explanation

The correct answer is A = 615.44 squared kilometers. To find the area of a circle, we use the formula A = πr², where π is approximately 3.14 and r is the radius of the circle. Since the question does not provide the radius, we cannot calculate the exact area. However, based on the given options, the closest answer is A = 615.44 squared kilometers.

9. Find the CIRCUMFERENCE of the Circle. Use 3.14 for  DIAMETER =  56 kilometers. 

Explanation

The circumference of a circle can be calculated using the formula C = πd, where C is the circumference and d is the diameter. In this question, the diameter is given as 56 kilometers. Plugging this value into the formula, we get C = 3.14 * 56 = 175.84 kilometers. Therefore, the correct answer is C = 175.84 kilometers.

Submit
10. Find the Area of the circle. Use 3.14 for  

Explanation

The correct answer is A = 452.1 squared inches. To find the area of a circle, we use the formula A = πr^2, where π is approximately 3.14 and r is the radius of the circle. Since the radius is not given in the question, we can assume that it is provided in another part of the question or context. By plugging in the given value of A = 452.1 squared inches into the formula, we can solve for the radius and find the correct answer.
