- 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
- Circumference and Area of Circles - Socratic
Questions What is the circumference of a 15-inch circle if the diameter of a circle is directly proportional to its radius and a circle with a 2-inch diameter has a circumference of approximately 6 28 inches? If the radius of a circle is 4cm, what is the area? How do you find the circumference of a circle with a diameter of 6 cm?
- A triangle has corners at # (2 , 9 )#, # (3 ,9 )#, and # (4 . . . - Socratic
Area of a triangle equals to half of a product of its perimeter by a radius of an inscribed circle: let #p= (a+b+c) 2# and #r# is a radius of an inscribed circle, then
- A solid consists of a cone on top of a cylinder with a . . . - Socratic
V_T=pir^2 (h_1 3+h_2) We need to calculate r in order to calculate the area of the base of the cylinder, hence we fill in the data given 150pi=pir^2 (39 3+17) We cancel the like term (pi) on each side 150cancelpi=cancelpir^2 (39 3+17) 150=r^2 (13+17) 150=r^2xx30 Divide both sides by 30 150 30=r^2 5=r^2 The formula of area of the base of a

- 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

Hi! I'm here to learn about Chemistry and Calculus! :)
- A triangle has corners at (6 ,8 ), (1 ,2 ), and (3 ,9 ). What is the . . .
Area of the triangle's circumscribed circle is 48 005 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 (6,8), (1,2) and (3,9) This will be surely distance between pair of points, which is
