Complete question:
A circle with radius 3 has a sector with a central angle of 1/9 pi radians
what is the area of the sector?
Answer:
The area of the sector = 
square units
Step-by-step explanation:
To find the area of the sector of a circle, let's use the formula:
Where, A = area
r = radius = 3
Substituting values in the formula, we have:
The area of the sector = square units
Answer:
a) 0.15
b) 0.2
c) 0.6
Step-by-step explanation:
40s+2bs+200=number of books needed
if we want 12 books and 8 stalls
b=12
s=8
solve
40(8)+2(12)(8)+200=
320+192+200=
712
needs 712 books
Answer:
no, its not a good fit because if 36 is 2 less than 38, -2(2) +38 cant equal 36 because -2 x 2 equals -4 not -2
Step-by-step explanation:
Angle 2 is 180-127=53 degrees
angle G is 90
triangle has a total of 180 degrees, so angle 1 is 180-90-53=37 degrees
