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.
I wanna say 6.93...but for sure i am wrong as the answer choices do not meet my guess.
The first step to finding the equation of a line when 2 points are known....
the first step would be to use the slope formula to find the slope of the line
Answer:
401.92 in ^2
Step-by-step explanation:
The surface area of a cylinder is
SA = 2 pi r^2 + 2 pi r h
We know the radius is 4 and the height is 12
SA = 2 * (3.14) * (4)^2 + 2 * (3.14)* (4) *12
100.48 + 301.44
401.92
is approximately 0.14!
