<span>You did not include the equations that you want to assess whether they can be used to solve for the radius (r).
Likely, the equation of the circumference, C = 2*Pi*r is included, if so => r = C / (2*Pi).
If you round Pi to 3.14, the equation may be written r = C / 6.28.</span>

Answer: 31.5 square units
Explanation:
The area of the rectangle is length*width = 7*3 = 21 square units
The area of the triangle is 0.5*base*height = 0.5*7*3 = 10.5 square units
The combined area is 21+10.5 = 31.5 square units
