Answer:
B. 
Step-by-step explanation:
We have been given a protractor and we are asked to find the measure of angle D.
We can see from our given protractor that the measure of angle D is 90 degrees as the ray OD crosses our protractor at 90 degrees.
Therefore, the measure of angle D is 90 degrees and option B is the correct choice.
Hi there!
The formula for the volume of a cone is V = 1/3(pi x r^2 x h). Using this formula, we can solve for the volume of the cone.
WORK:
V = 1/3(3.14 x 6.5^2 x 14)
V = 1857.31 / 3
V = 619.10 cm^3
ANSWER:
A) 619.10cm^3
Hope this helps!! :)
If there's anything else that I can help you with, please let me know!
1 / cos^2 O - 3 / cos O - 2 = 0
1 - 3 cos O - 2 cos^2 O = 0
2 cos^2 O + 3 cos O - 1 = 0
cos O = 0.2807 , -1.78 ( -1.78 cannot be a solution)
O = 74 degrees (from 0.2807) another solution is 360-74 = 286 degrees
Its D
