Answer:
It should be 21.1
Step-by-step explanation:
Area of full circle= πr^2
Area of a quadrant= πr^2/4
=(3.5)^2π/4
=12.25π/4
=3.06πcm squared.
Answer:
To divide, use / instead of \.
Examples: 1+2, 1/3+1/4, 2^3 * 2^2
(x+1)(x+2) (Simplify Example), 2x^2+2y x=5, y=3 (Evaluate Example)
y=x^2+1 (Graph Example), 4x+2=2(x+6) (Solve Example)
Step-by-step explanation:
example
The rate is 274m/17s = 16.1176m/s
