Cylinders a and b are similar solids. the base of cylinder a has a circumference of 43 units. the base of cylinder b has an
area of our units
the dimensions of cylinder a are multiplied by what factor to produce the corresponding dimensions of cylinder b?

The formula for the circumference of a circle is

 C = 2π·r

or

 r = C/(2π)

The radius r of cylinder A is

 r = (4π)/(2π) = 2

The formula for the area of a circle is

 A = π·r²

or

 r = √(A/π)

The radius of cylinder B is

 r = √(9π/π) = 3

The dimensions of cylinder A must be multiplied by 3/2 to produce the corresponding dimensions of cylinder B.

think about it deeply and passionately about this property

i am sorry

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !
