Which problems result in a positive number? Choose all answers that are correct. A. –4.6 • 1.6 B. –10 • (–5.2) C. 8.4 ÷ 2 D.

Answers

Answer 1

Answer: Well you can automatically eliminate, A, because when you multiply one number that's positive and another number that's negative the result is always going to be negative.
However, when you multiply two negatives the result is always positive!

So, the only ones up there that would result in a positive number is B and C

***D. was not posted so I cannot determine that one!

B) 200.96 because the area of a circle is 2*Pi* your radius which is 8 so you do 2 times 3.14 times 8 and you get 200.96 hope i helped!!

The answer is B :) Hope I helped you.

Answer:

The radius of the can, rounded to the nearest hundredth, is 530.66.

Step-by-step explanation:

We want to do the reverse of the formula for V, which is pi(r)^2(h).

to isolate r.

Let's start by writing an equivalent equation to V = $\pi$ $r^(2)$ h by solving for r

$\sqrt[]{(V * \pi )/(h) } = r$

Now, substitute and solve for r

1014 * 3.14 / 6 = 530.66

if the length of a radius of a circle is doubled how does that affect the circumference and area explain

Answers

If the length of the radius in a circle is increased (or in this case, doubled) the circumference changes along with it. Because, remember; radius is half of circumference, so if the radius changes it only makes sense for the or circumference to change as well. To find the area of the circle you need the circumference, and if the radius has been changed, so will the circumference, and if the circumference has changed, so will the area. Get it? Hope I helped
