0.333 x 81
=26.973 answer
Answer: Add the equations to eliminate k
Step-by-step explanation:
Adding the equations, you get 2b=18, which you can solve for b. Afterward, you can substitute this value of b back into either equation to solve for k.
To calculate the area it is pi*r^2
so since r = 1/2 d
2.5^2 * pi = area
or
19.625
