Answer:

the area is quadrupled

Step-by-step explanation:

Consider the area (A) of the circle using both radii

r = 3

A = π × 3² = 9π

r = 6

A = π × 6² = 36π ← 4 times the area with r = 3

Solution: It would be quadrupled because radius controls to axis (height & width) meaning if you double two (2 x 2) you get four (4).

Answer:

The range here is 85

Step-by-step explanation:

Here, we want to calculate the range of the data

Mathematically, the range is defined as the difference between the lowest value and the highest value in the dataset

From the given data points, the highest value is 189, while the lowest value is 104

So the range is the difference between the two which is;

189-104 = 85

1. The structure of the supports for the hill consists of steel beams that

Darina [25.2K]

a) Parallel for both line segments have the same slope = -5/4

b) 55º

Step-by-step explanation:

a) To verify the parallelism of these line segments, It's necessary to find the slope of each one. Parallel lines share the same slope value:

$m_{BC}=\frac{0-150}{120-0}=-\frac{-5}{4}\\m_{AD}=\frac{0-125}{100-0}=-\frac{5}{4}$

b) If ∠DAB = 125°, what is the measure of ∠CBA? Justify your reasoning.

Those beams do not form a parallelogram because:

Using the formula of distance between those points

$d=\sqrt{(y_{2}-y_1)^{2}-(x_{2}-x_{1})^2$

$\overline {AB}=25\: \: \: \overline{CD}=20\: \: \overline{AD}=160 \: \: \overline{BC}=192$

So this is a trapezoid. And two adjacent angles within a trapezoid are supplementary, so If ∠DAB = 125º then 180 - ∠CBA=55º
