Answer:
20+40+2+4 or 24 + 42
Step-by-step explanation:
The first equation is 1x + 1y = 8, satisfied by all four answers.
The second equation is 2x+3y =36; checking we find
2(-12)+3(20) = -24+60 = 36
Choice C
Solve for h by simplifying both sides of the equation,then isolating the variables
2πrh,
h=-2πr^2+sa
Answer: 9.42 cm.
Step-by-step explanation:
Length of arc is given by :-
, where r= radius and x= central angle subtended by arc.
As per given , we have
Then, the length of arc will be :
Hence, the length of arc is 9.42 cm.
To find corresponding angles and sides, you look at the name of the figure and see which one correlates.
