Step-by-step explanation:
area of circle= πr²
3.14×7×7
153.86 is the required area
13. Picture is cut off. Insufficient information is shown.
14. ST = 2×(XY)
8z +3 = 2(3z +2)
2z = 1
z = 1/2
The answer is 42... you add 56 and 82 then subtract that sum from 180
36 because the rest are prime #'8
One way to see if two ratios are proportional is to write them as fractions and then reduce them. If the reduced fractions are the same, your ratios are proportional.
