Answer: Defualt
Step-by-step explanation: Dan
What is the equation? I cannot solve it without the equation.
s = 6 + e
s + e = 28
We can use this system of equations to find the exact values of s and e.
We have a current value of s, so we can find the exact value of e now.
e + e + 6 = 28
<em><u>Combine like terms.</u></em>
2e + 6 = 28
<em><u>Subtract both sides by 6.</u></em>
2e = 22
<em><u>Divide both sides by 2.</u></em>
e = 11
Now we have an exact value of e, and can solve for the value of s.
s = 6 + 11
s = 17

Answer:
866.64
Step-by-step explanation:
40/2 = 20
A = πr²
3.14*20² = 1256
52/2 = 26
3.14*26² = 2122.64
2122.64 - 1256 = 866.64
