Answer:

diameter

circumference

\pi

diameter

Step-by-step explanation:

First, find the length of the diameter (d) and the length of the circumference of the circle (c).

Next, divide the length of the circumference c by the length of the diameter d and set up an equation

\dfrac{c}{d}=\pi

where the ratio equals to \mathbf{\pi } (the definition of \pi)

Then, solve the equation for the circumference c:

c=\pi d

Finally, substitute 2 times the radius for the diameter

c=\pi \cdot 2r=2\pi r

A square has an area of 16x^2 square inches. If the sides of the square were to increase by 2 units, what is the new area of the
kykrilka [37]

Answer:

16x² + 64x + 64

Step-by-step explanation:

Given

A = 16x²

Increasing the sides by 2, substitute x = x + 2 into A

A = 16(x + 2)² ← expand factor using FOIL

   = 16(x² + 4x + 4 ) ← distribute

   = 16x² + 64x + 64
