Answer:

B. The ratio of the area of the scale drawing to the area of the painting is 1:16

C. The ratio of the perimeter of the scale drawing to the perimeter of the painting is 1:4

Step-by-step explanation:

The ratio of the area of similar figures/shapes = the square of the ratio of any of their side lengths

Since the scale drawing of the rectangular painting and the actual rectangular painting are similar, therefore,

The ratio of the area of the scale drawing to the painting = 1²:4²

= 1:16

Also, comparing the ratio of the perimeter of the scale drawing to the perimeter of the painting will be the same as the scale factor = 1:4

What is the measure of o
Helga [31]

Answer:

D

Step-by-step explanation:

We need the formula for arc length (in radians) to solve this problem. The formula is:

s=r \theta

Where

s is the arc length

r is the radius of the circle

\theta is the intercepted angle

In this diagram, we can see that  \theta  is beign intercepted by the big arc with measure 20 cm. So arc length, s, is 20

Also, if we look, we see that the radius is 5 cm, so r = 5

Now, we substitute into formula and find \theta:

s=r\theta\\20=5\theta\\\theta=\frac{20}{5}\\\theta=4

This is given in radians, so \theta is 4 radians

D is the correct answer choice.
