Here we have a problem to find the area of a crater (the circle's lateral area, not the volume) based on a meteor measuring 10 miles in diameter (the diameter of the crater). To find the area, we use an equation to find the area of the circle:A = πr^2Where A = area and r = radius.To find the radius, we simply divide the diameter in half, so r = 5. We set π = 3.14, and now we substitute the variables with our values.A = (3.14)(5^2)A = (3.14)(25)A = 78.5 mi^2The area of the crater is 78.5 square miles.~ Azaler
