  • Question #98679 - Socratic
    The area of the circle is 9picm^2 or 28 26cm^2 From the perimeter (circumference) of a circle, we can calculate the radius, which we can then use to calculate the area of the circle The formula for circumference of a circle is: C=2pir, where C=Circumference, and r=radius Using the given data: 6pi=2pir Cancel the like terms on both sides 6cancelpi=2cancelpir Divide both sides by 2 3=r Now
  • A triangle has corners at (7 ,3 ), (5 ,8 ), and (4 ,6 ). What is the . . .
    Area of triangle's circumscribed circle is 25 16 If the sides of a triangle are a, b and c, then the area of the triangle Delta is given by the formula Delta=sqrt(s(s-a)(s-b)(s-c)), where s=1 2(a+b+c) and radius of circumscribed circle is (abc) (4Delta) Hence let us find the sides of triangle formed by (7,3), (5,8) and (4,6) This will be surely distance between pair of points, which is a=sqrt

  • Question #08cc1 - Socratic
    See a solution process below: The formula for the circumference of a circle is: C = 2pir Where: C is the circumference of the circle r is the radius of the circle However, we also know; 2r = d Where: r is the radius of the circle d is the diameter of the circle We can rewrite the equation for the circumference of a circle as: C = 2pir = 2rpi = pid Substituting for C and solving for d gives
