Answer:
3.14
Step-by-step explanation:
A quarter circle is just 1/4 of an entire circle's area. Since you know the radius is two, simply find the area of the entire circle and divide by 4.
4pi/4 = pi
3t + 4s = $83
4t + 1s = $50 (x 4)
16t + 4s = $200
3t + 4s = $83 (minus them£
13t = $117 (divide by 13)
t = $9
sub t into first equation.
3 x 9 = 27
27 + 4s = $83
4s = $56
s = $14
t = $9
s = $14
