What are the major arcs of o0 that contain point B?
1 answer:
Answer:
see below
Step-by-step explanation:
The four major arcs that include B will be the remainder of the circle after each minor arc is excluded.
Excluding minor arc AB, we have major arc BCA.
Excluding minor arc BC, we have major arc CDB.
Excluding minor arc CD, we have major arc DAC.
Excluding minor arc DA, we have major arc ABD.

Answer:
1.03
Step-by-step explanation:
To find the volume of a prism, find the area of the base and multiply it by the height.
The base is an octagon. The area is found . Substitute a = 0.5.
The volume is 1.21*2.5 = 3.025.
However, there are three holes drilled out half way which each have volume 0.06.
The volume is found as V = πr²h. Substitute r = 0.125 which is half the diameter of 0.25. Since they go half way, the height is h = 1.25.
V = π(0.125)²(1.25) = 0.06.
Since there are 3, they equal 3*0.06 = 0.18.
Subtract this from the volume.
1.21 - 0.18 = 1.03
