sara is working on a geometry problem in her algebra class. the problem requires sara to use the two quadrilaterals below to answer a list of questions.
part a: for what one value of x are the perimeters of the quadrilaterals the same? (hint: the perimeter of a quadrilateral is the sum of its sides.)
part b: for what one value of x are the areas of the quadrilaterals the same? (hint: the area of a quadrilateral is the product of its base and height.)

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
