Answer:
156
Step-by-step explanation:
Each triangle has an angle sum of 180 degrees, so the sum of the interior angles of the 15-gon must be (n-2) 13 × 180 = 2340 degrees. Since the 15-gon is regular, this total is shared equally among the 15 interior angles. Each interior angle must have a measure of 2340 ÷ 15 = 156 degrees.

Answer:
86,000
Step-by-step explanation:
Find the thousands place value (will be bolded and underlined):
8<u>5</u>,634
Look to the place value directly to the right of what you are looking for. In this case, it is a 6. If the number is 5 or greater round up, if 4 or less, round down:
85,634 rounded to the nearest thousand is 86,000.

If you would like to know the volume, you can calculate this using the following steps:
volume = 4/5 * 3 1/2 * 3 1/8 = 4/5 * 7/2 * 25/8 = (5*7)/(2*2) = 35/4 = 8.75
The correct result would be 35/4.
