Answer:
20.424
Step-by-step explanation:
Given words can be written as
Eight and eighty-eight hundredths = (8+)
=
= 8.88
Two and three tenth = (2+)
=
= 2.3
Now multiply them
i.e 8.88 × 2.3 = 20.424
So 20.424 is the Answer
X²-18x+81 + y²+8y+16 = -5+81+16=92
(x-9)² + (y+4)² = (2✓23)²
circle centered at (9,-4) with radius 2✓23
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
32,870 is the answer. Hope this helps!
