The tangent to the curve y=4/x at the point p(1, 4) cuts the x-axis at point a and the y-axis at point b. calculate the area of the triangle aob where o is the origin.

Circle a has a diameter of 7 inches, a circumference of 21.98 inches, and an area of 38.465 square inches. the diameter of circle b is 6 inches, the circumference is 18.84 inches, and the area is 28.26 square inches. part a: using the formula for circumference, solve for the value of pi for each circle. (4 points) part b: use the formula for area and solve for the value of pi for each circle. (4 points)
