I know that ariel is wrong because 3x^3 is higher power than y^2
3x^3 goes first
then the mixed term -4x^2y
then the y^2
then the 2
marcus is right
Answer:
Area of sector = 21.195 cm²
length of arc = 4.71 cm
Step-by-step explanation:
Given:
Radius of circle (r) = 9 Cm
Angle at O = 30°
Find:
Area of sector.
length of arc.
Computation:
⇒ Area of sector = [θ/360]πr²
Area of sector = [30/360]3.14(9)²
Area of sector = 21.195 cm²
⇒ length of arc = [θ/360]2πr
length of arc = [30/360]2(3.14)(9)
length of arc = 4.71 cm
2(x+3) Because
You need to factor out the 2 from the expression which makes it 2(x+3)
