Answer:
77y-44
Step-by-step explanation:
when you expand this type of equations you just multiply the coefficient of y and the number by -11
so:
-11*4=-44
-11*-7=77 (note: negative multiplied by negative equals positive)
so the equation now became
-44+77y
exchange places now its:
77y-44
Answer:
the 1st and 4th one is the answer
Step-by-step explanation:
The area of a sector of a circle can be calculated by using this formula:
A=(n/360)*pi*r^2
where n is the measure of the central angle of the sector in degrees. Since we are already given with the measurement of the central angle, we can substitute this to the above formula:
A=(30/360)*pi*r^2
Taking the value of pi as 3.14, then
A=(1/12)*3.14*r^2
A=0.2617*r^2
Just plug in the value of r. and you will get the area of the sector. Hope this helps!
