Answer:
approximately 21, when rounded to nearest tenth.
Step-by-step explanation:
First, let's find the measure of angle BAD. Angles BAD and DAC add up to 180 degrees, so 180-57= 123 degrees. Now, let's find the circumference of the circle. The circumference is diameter * π, which is 19.6(π). Then, the ratio is 123/360, so multiply 19.6(π) by 123/360, and you get 21.0381988...... which simplifies to 21 (rounded to nearest tenth)
Thank you for positing your question here. Possible answer to the problem is that the10 ones is equal to 1 ten, the ungrouped number 4,000 + 900 + 10 which is total of 5,000. I hope my explanation helps.
