Given:
Arc length = 8 inches
radius = 3 inches
find the measure of the central angle.
Arc length = radius * central angle
central angle = arc length / radius
central angle = 8 inches / 3 inches
central angle = 2.667 (radian)
Central angle in degrees = 152.88°
Circumference of the circle = 2 * 3.14 * 3 inches = 18.84 inches
1 circle = 360° / 18.84 inches = 19.11° per inch
19.11° per inches * 8 inches of arc length = 152.88°
You would know 4×5=20 so just add 2 more zeroes cause there is a zero in 40 and in 50
hope this is what you're looking for and made sense
B. and C. a.k.a
B. Some ratios are not fractions &
C. All fractions are ratios
btw i just did this one XD
Answer:
251.2
I used 3.14 as pi
Step by step explanation:
SA= 2(pi*r²) + (pi*d)h
SA= 2 (
* 4² ) + (pi*8)*6
<u>you could also do this:</u>
SA=2πrh + 2πr²
Answer: 300
You need to change 9% into a decimal so it would be 0.09
Then divide 27 ÷ 0.09 = 300
So 9% of 300 is 27
