What is the length of an arc if we know the radius of curvature is 12 in. and the area of the sector created is 252 in. sq.

I'll do the first one for you. it isn't very hard at all.on number one, you have (50 × 3), which equals 150, and (3 × 3), which equals 9. after you establish that, you add 150 and 9 together. so, (150 + 9) equals 159.this means that 53 × 3 = 159.

Move the decimal behind it
