What is the approximate circumference of a circle with a radius of 6.5 meters? use π ≈ 3.14. a. 13 meters b. 20.4 meters c. 40.8 meters d. 132 meters

Hi there! To find the circumference of a circle, you multiply pi and the diameter. The radius is 1/2 of the diameter and 6.5 * 2 is 13. The diameter is 13 meters. Multiply 13 by 3.14 to get the circumference. 13 * 3.14 is 40.82 or 40.8 when rounded to the nearest tenth. The circumference of the circle is 40.8 meters. The answer is C: 40.8 meters.

Number 5 is 50 degreesnumber 6 is 45 degreesnumber 7 is 60 degreesnumber 8 is 45 degrees

Answercounterclockwise rotation about the origin by 180 degrees followed by reflection about the y-axisexplanationthe given figure has verticesrecall that for counterclockwise rotation about the origin, when we rotate figure pqrs counterclockwise through an angle of 180° about the origin, the coordinates will becomenext, we reflect in the y-axis by negating the x-coordinates of the resulting figure to obtain,therefore the correct answer is c
