Answer: A union B = B
The first one should’ve said A intersects B = A because the entirety of A exists in B
Answer:
Surface area of sphere = 4πr²
r = radius
radius = diameter /2
= 12/2
= 6units
Surface area = 4π×6²
= 144π
= 452.4 square units
Hope this helps.
Answer:
Step-by-step explanation:
A perpendicular bisector is a special kind of segment, ray, or line that. (1) intersects a given segment at a 90° angle, and. (2) passes through the given segment's midpoint. Segment CD is the perpendicular bisector to segment AB. We derive two important theorems from the characteristics of perpendicular bisectors.
Answer:
72m^3
Step-by-step explanation:
l x w x h
l = 2
w = 9
h = 4
2 x 9 x 4 = 72
10 the second power is 10². 10²=10*10=100. 100*18.72=1,872. Hoped I helped. :)
