a circular table has a raduis of (x-1)m..find its area
280 divide by 70
clearly its area is π(x-1)^2 m^2
To find the area of a circular table with a radius of (x-1)m, we can use the formula for the area of a circle, which is A = πr^2.
In this case, the radius is (x-1)m. So, we substitute this value into the formula:
A = π(x-1)^2
To simplify the expression, we need to expand:
A = π(x^2 - 2x + 1)
Then, we can distribute the π through the parentheses:
A = πx^2 - 2πx + π
So, the area of the circular table is πx^2 - 2πx + π square meters.
