Use guess-and-check to find two numbers that have the sum of 8 and a difference of 2. a. 6 and 2 b. 6 and 4 c. 4 and 4 d. 5 and 3

D

Step-by-step explanation:

Option A, does 6 and 2 added makes 8? Yes

does 6 and 2 subtracted makes 2? No

Option B, does 6 and 4 added makes 8? No

does 6 and 4 subtracted gives 2? Yes

Option C, does 4 and 4 added gives 8? Yes

does 4 and 4 subtracted gives 2? No

Option D

Does 5 and 3 added give 8? Yes

Does 5 and 3 subtracted give 2? Yes

So we can see, Option D is the correct answer because it satisfies both conditions.

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 !
