Circle A has radius 4 feet circle B has radius 9 feet What is the ratio of the area of circle A to the area of circle B?
Area(A)/ Area(B) = pi*rA2/pi*rB2 = rA2/rB2 = 16/81
If circle A has 4 times the radius of circle B how many times bigger is the area of circle A than circle B?
16
Circle A has a radius that is twice the length of circle B What is an accurate statement about the areas of both circles?
Circle A has more area than B
If circle A has a radius of 3 cm and circle B has a radius of 4 cm and circle C has the same total area as circles A and B combined hoe do you determine the radius of circle C?
The formual for area is: A = πr2 so the area of circle A (assuming π=3.142) is 28.278cm2, and the area of circle B is 50.272cm2.Their combined area of 78.55cm2 is the area of circle C.The formula for radius is: square root of A/π78.55 ÷ 3.142 = 25, the square root of 25 is 5The radius of circle C is 5cmArea of Circle A = π32 = 9πArea of Circle B = π42 = 16πArea of Circle C = 9π + 16π = 25πLet r = radius of Circle C thenπr2 = 25π : r2 = 25 : r = 5.
What is the surface area of a cylinder whose height is A and radius of B?
(2*PI*B*A) + 2(PI*B^2) Its the perimeter of the circle which B creates times the height + two of the area of the circle which B creates [top and bottom]

The base area of a cone or cylinder with radius r is B equals?
The base of a cone or cylinder is a circle. It the radius is r then the base area B=Pi(r2)
How do you find the area and perimeter with no numbers just letters?
enter-net ______________ It depends on the shape of the area you are referring to. 1) For a square with side "a", the area is (a squared) and the perimeter is 4 x a 2) For a rectangle with sides "a" and "b", the area is a x b and the perimeter is 2 x (a + b) 3) For a circle with radius "a", the area is pi x (a squared) and the perimeter (for a circle it is the circumference) is 2 x pi x r
