Answer: 38.5 cm^2
Step-by-step explanation:
Length of wire = 7*2 + 4*2 = 22 cm
Radius of Circle = 22/(2pi) = 3.5 cm
Area of Circle = (3.5)^2*pi = 38.5 cm^2
A + b +c = 75; where a is the greatest number; b is the middle number; c is the least number;
a = 2 * c;
b = 3 + c;
then, 2 * c + 3 + c + c = 75 => 4 * c = 72 => c = 72 / 4 => c = 18 => a = 2 * 18 => a = 36; b = 3 + 18 => b = 21;
When two the same numbers under the square root multiply, they are equal to the value under the square root, for example √2⋅√2 = 2. So then we have:
3√2⋅2√8⋅√3⋅√6 = 3⋅√2⋅2⋅√(2⋅2⋅2)⋅√3⋅√(3⋅2) = 3⋅2⋅√2⋅√2⋅√2⋅√2⋅√2⋅√3⋅√3 = 3⋅2⋅2⋅√2⋅3 = 36⋅√2
or if the bolded 2 from above is also the square root, then the solution is:
3√(2⋅2)√(2⋅2⋅2)⋅√3⋅√(3⋅2) = 54
