Wesley has a baseball sticker with a radius of 2.3 centimeters. Determine the circumference of his baseball sticker to the neare
1 answer:
Answer:
14.4 centimeters
Step-by-step explanation:
The formula for circumference is: . In this case, the r (radius) is 2.3. Multiply it by 2 to get the diameter or 4.6. Then multiply 4.6 x
(pi) to get 14.444. This rounded to the nearest tenth of a centimeter is 14.4.
Note:
I used 3.14 for (pi).

Let's begin noting that a triangle is isosceles if and only if two of its angles are congruent. We can thus find the angle <ABP, recalling that the sum of the interior angles of a triangle is equal to 180°.
Finally, let point K be the intersection between segments BC and PQ, and let's note that the triangle PQB is a right isosceles triangle, since all the angles in a square are equal to 90°, and the two triangles APB and BQC are congruent.
Therefore, the angle BKQ is equal to 180-50-45=85°.
Of course angle BKP=180-85=95°.
