Hello,
if tan x=√3/3 then x=30°+k*180° k: integer
The formula for area of a circle is π × radius², and the radius is half of the diameter, which means that your final expression is π × 6² = 36π = 113.1 inches². I hope this helps!
70 X 10 =700
Therefore, it is 10 times greater than 70.
The answer is D
