Step-by-step explanation:
Arc length = fraction of the circle * circumference
Arc length = fraction of the circle * 2 * pi *r
3/4 pi = fraction of the circle * 2 * pi *5
3/4 pi = fraction of the circle *10 pi
Divide each side by 10pi
3/4 pi
-------- = fraction of a circle
10 pi
3/40 = fraction of a circle
A circle is 360 degrees
3/40 = x/360
Multiply by 360
3/40 *360 = x
27 = x
Answer:
Step-by-step explanation:
It is a sphere with radius r = 5 cm
volume = (4/3)πr³
= (4/3)π(5³)
≅ 523.60 cm³
1.8 = $1.80.
1.08 = $1.08.
