ERROR ANALYSIS Describe and correct the error in finding the sum. X^3- 4x^+ 3
+-3x^3+ 8x - 2
-2x^3 + 4x^+ 1

The sum of 3 and 2 is not 1.

The sum of x' and 3x is not 2x} .

The terms x and
3x are not like terms and cannot be added.

• The terms - 4x2 and 8x are not like terms and cannot be added.

The correct answer is

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 !

what is the answer?

a

step-by-step explanation:

m∠5 + m∠3 = m∠1   is true.

m∠5 + m∠6 = 180 is true

m∠2 +m∠3 = m∠6   is true

m∠2 +m∠3 +m∠5 = 180   is true
