Answer:
80.78°
Step-by-step explanation:
When the 30 cm long string will be bent in the form of a sector it's two sides will be radii of the sector and lower part be the arc. Length of the arc can be found as given below.
Length of the string = 30 cm
radius of sector (r)= 8.8 cm
Length of the arc (l) = 30 - 2*8.8 = 30 - 17.6 = 12.4 cm
Let the sector makes angle at the centre of the circle.
Formula for length of arc of a sector is given as:
Plugging the values of l and r in the above formula, we find:
Answer: -4 and -2
Step-by-step explanation:
No need to explain, it is a fairly simple question.
The are 9 pieces of data in the set so we have:
(27+32+14+19+24+26+22+32+29)/9 = 25
25 is the mean of the set of data.
I'all say the 2 line because if all those zeros are there then it will add to a zero. and Happy Valentine dat
