150-56=94
20*3 = 60
94-60 = 34
34-12= 22
The arc length formula is s = r*theta, where r is the radius and theta is the central angle in radians (not degrees).
Here, r = 3.4 cm and the central angle is 46 degrees. We MUST convert this measure 46 degrees into radians, using the conversion factor derived from 180 degrees = pi radians:
arc length = r*theta = (3.4 cm)*(46 degrees)*(pi rad) / (180 degrees) =
2.730 cm (to the nearest thousandth)

A cylinder's volume is =
π r² h,
and its surface area is =
2π r h + 2π r².
Ryan payed $125 per month. Steps below.
7,500 - 3,000 = 4,500
4,500 / 36 = 125.
