Answer:
19. C
20. D
21. B
22. A
Step-by-step explanation:
If an angle is subtended from an arc and it goes to the opposite end of the circle, the angle is HALF of the measure of the arc. If it goes to the center, it is SAME measure as arc.
19.
Arc BC is DOUBLE of Angle BAC, so
78 * 2 = 156
Answer is C
20.
Arc BEC is DOUBLE of Angle BAC, so
114 * 2 = 228
Answer is D
21.
Angle ABC is HALF of Arc AC, so
Angle ABC = 110/2 = 55
Answer is B
22.
Angle ABC is HALF of Arc AC, so
Angle ABC = 218/2 = 109
Answer is A
Given is triangle with base = 10 cm and perpendicular height = 3 cm.
We know the formula for area of triangle is given by :-
Area = 
× (Base) × (perpendicular height)
Area = × (10) × (3)
Area = 
Area = 15 cm²
So, final answer is 15 cm².
Well is the length is 4 ft, and 1 ft is 12 inches we need to do 12×4, which is 48.
So now we know that the length is 48, and the height is 4, so it would be 48×4, which gives us our answer, 192 inches!
Answer:
3937.5 or 3938 after round-off
Step-by-step explanation:
11 minutes 15 seconds = 11.25 minutes
5 members of the family shower 7 times a week for 11.25 minutes
=total of 393.75 minutes
393.75 times the amount of water used which is 10 litres becomes 3937.5
