Area of a circle = pi r^2 = pi * 12^2 = 452.4 in^2 to nearest tenth.
Answer:
1. Multiply the value of the first variable by one of the original equations to solve for the second variable.
2. Solve for one of the variables.
3. Substitute the value of the known variable into one of the original equations to solve for the unknown variable.
Step-by-step explanation:
Answer:
Around 60.32 squared
Step-by-step explanation:
Area = (3√3 s2)/ 2 where s is the length of a side of the regular hexagon.
subsitute x = 6 into the lengths
3(6) -7
18 - 7
11cm
(6) + 5
11cm
therefore it is a square when x = 6 because the sides are all equal
