Show that the tangent at the point P, with parameter t, on the curve x=3t, y=2t^3 has equation y=tx - t^3.Prove that this tangent will cut the curve again at the point Q with coordinates (3t^2/4,t^3/4).Find the coordinates of the possible positions of P if the tangent to the curve at P is the normal to the curve at Q​

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)
