The radius of the Outer circle (with r₂) is 6 and the radius of the inner circle (with r₁) is 2. When objects are similar, they have a proportional relationship. If we take the outer circle and squeeze by one third, we get a radius of 6 x 1/3 = 2. On the other hand, if we start with the inner circle and stretch it by 3, we get a radius of 2 x 3 = 6.


Thus, to make r₂ similar, we use a scale factor of 1/3. The third choice is best.

Im not sure where to start with this one...<br>​
Nina [5.8K]
The volume of a cube is side length cubed (s^3)
So if you know the volume then take the cube root of 1/512... which is 1/8

So each side of the cube is 1/8.

There are 6 congruent sides on a cube (picture a “dice”). Do the area of each side would be (1/8)(1/8)= 1/64 then multiply that area by 6 and reduce ... you get 6/64 = 3/32 for the surface area

If you roll two fair six-sided dice, what is the probability that at least one die shows a 333?
Vesna [10]

Answer:

1/3(0.3333333333%)

Step-by-step explanation:

There are six sides, and you can only land on one at a time on each die,  so there is a one-in-three chance of landing on a three.
