Step-by-step explanation:
Hey there!
Here;
Diameter (d) = 13 ft
Radius (r) = 13/2 = 6.5 ft
Now,
Area of a circle= πr²
= (22/7)*(6.5)²
= 132.78 ft²
Therefore, the area is 133 ft².

Step-by-step explanation:
The area formula for a trapezoid is , where is the trapezoid's area, and are the trapezoid's bases, or parallel sides, and is the trapezoid's height.
We are given that , and from the diagram, we see that . Therefore, all we have to do to find is substitute the given values into the area formula. Therefore:
(Substitute the given values into the equation)
(Simplify RHS)
(Divide both sides of the equation by to get rid of 's coefficient)
(Simplify, Symmetric Property of Equality)
Hope this helps!
