Answer:
The correct options are a,b.
Step-by-step explanation:
The area of sector of a circle equals
Area of a sector = 
where
is the angle subtended at the center by the sector
is the radius of circle
This indicates that area of the sector depends on:
1) Radius of circle
2) Angle subtended at the center by the sector
3) Area of sector does not depend on pi.
Also if we know the area of the sector only we cannot calculate area of area of whole triangle as we need one more information either angle of the sector and vice versa.
We know that the original price is 160 and has increased to 248. To calculate the increase, divide. But first lets find the difference 248-160 =88
The percentage increase is 55%.
Equation is
x-6=8
x=8+6
x=14
X equal to 14
Answer: 12 boys: 13 Girls
Step-by-step explanation: Nothing much really.
We have an equation for the surface area of a rectangular prism:
A= 2 (w*l+ l*h+ h*w)
Plug l= 16 in, w= 12 in, and h= 5 in into the above equation, we have:
A= 2 (12 in*16 in+ 16 in* 5 in+ 5 in* 12 in)= 664 in^(2).
The final answer is 664 in^(2).
Hope this is helpful~
