R = 60
60^2 * pi = 3600 * pi
angle = 30°
3600pi / 30 = 120pi
the answer is 120 * pi
Well, one quarter of 20 is 5 (because 20 ÷ 4 = 5). so, to find 3 quarters, we multiply 5 times 3.
5 × 3 = 15, so 3 quarters of 20 is 15.
(f - g) (144) Multiply 144 by both variables in the other set of parentheses.
[(144) (f) - (144) ( g)] Simplify
144 f - 144g
Answer: 53.13
