The area of sector is given by:
A=θ/360πr²
θ=210°
r=10/2=5 cm
thus the area will be:
A=210/360×π×5²
A=210/360×3.14×5²
A=45.8 cm²
Rectangle's perimeter formula is p=2(length+width)
2(9x+8x)=68
17x=34
x=2
length is 9(2)=18 feet
width is 8(2)=16feet
D because perpendicular lines intersect at a right angle and D is the only shape with right angles.
Answer:
C
Step-by-step explanation:
- The domain is all the x numbers for each point
- So -5,-4,0,2,4
