What is the area of a circle whose diameter is given by the expression 10x?
Area = pi * r^2
diameter = 2r, r = d/2
d = 10x, r = 10x/2 = 5x
A = pi * (5x)^2
A = 3.14 (25x^2)
A = 78.5 x^2
35+ 6x <29-2
State wheither the given pair of lines are parallel.
To find the area of a circle, you need to know either its radius or its diameter. In this case, the diameter of the circle is given by the expression 10x.
To find the radius from the given diameter expression, you would divide it by 2. So, the radius of the circle would be (10x)/2, which simplifies to 5x.
Now that you know the radius is 5x, you can find the area of the circle using the formula A = πr^2, where A is the area and r is the radius.
Plugging in the value of the radius, the area of the circle would be A = π(5x)^2.
Expanding this expression, you get A = π(25x^2).
Therefore, the area of the circle whose diameter is given by the expression 10x is 25πx^2.
