Answer:
14 meters²
Step-by-step explanation:
Since the formula to find the diameter is , we need to first find the radius, which can be
if we take the formula for the area of a circle and isolate the radius. After simplifying
to 7 and multiplying that by 2, we get the circle's diameter of 14 meters. Hope this helps!

Answer:
Step-by-step explanation:
The equation is:
a x - c = b x + d
so we subtract b x from both sides to group the terms that contain x on the left:
a x - b x - c = d
add c to both sides to isolate the terms in x on the left:
a x - b x = d + c
extract "x" as common factor on the left using distributive property backwards:
x (a - b) = d + c
divide both sides by the quantity (a - b) to isolate the "x":
x = (d + c) / (a - b)
or:
