Question 2

mylen [45]

Answer:

Part A: OC. 16π square inches

Part B: OC. 36π square inches

Step-by-step explanation:

Part A:

Given

Diameter of circular picture = d = 8 inches

We need to find the radius first to find the area

So,

Rdius = r = d/2 = 8/2 = 4 inches

$Area = \pi r^2\\= \pi *(4)^2\\= 16\pi\ square\ inches$

Therefore, option C is the correct answer..

Part B:

As two inches frame is added around the picture, the diameter will become 8+4 =12 inches

The new radius will be:

r = 12/2 = 6

So,

$Area\ with\ frame = \pi r^2\\=\pi *(6)^2\\=36\pi\ square inches$

Therefore, option C is correct ..

Find the equation of a line that is parallel to the line x= 19 and contains the point (-4,7)

VashaNatasha [74]

Answer:

x = - 4

Step-by-step explanation:

x = 19 is a vertical line parallel to the y- axis

A line parallel to it has the equation

x = c

where c is the value of the x- coordinates the line passes through

The line passes through (- 4, 7 ) with x- coordinate - 4 , then

x = - 4 ← equation of parallel line
