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 (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
A triangle has corners at (4 ,6 ), (2 ,9 ), and (8 ,4 ). What is the . . . Area of circumscribed circle is 194 5068 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 (4,6), (2,9) and (8,4) This will be surely distance between pair of points, which is a=sqrt
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
Circumference and Area of Circles - Socratic If the diameter of a circle is #1 3*10^-12# meters, then what is its radius? If the diameter of the circle is 5 cm, what is the circumfrence and area of the figure?
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
Circle A has a center at # (1 ,4 )# and an area of #28 pi#. Circle B . . . Circle A has a center at # (1 ,4 )# and an area of #28 pi# Circle B has a center at # (7 ,9 )# and an area of #8 pi# Do the circles overlap? If not, what is the shortest distance between them?
