Both circles have the same center. What is the area of the shaded region?
17.2 mm
r=12.6 mm

  2290 mm²  or  2289.94 mm²

Step-by-step explanation:

The radius of the outer circle is the sum of the inner radius and the width of the shaded area: 12.6 mm +17.2 mm = 29.8 mm.

The shaded area is the difference between the area of the outer circle and the area of the inner circle. The area of either circle is given by the formula ...

  A = πr²

so, the area of the ring is ...

  A = π(29.8 mm)² -π(12.6 mm)² = π(888.04 mm² -158.76 mm²)

  A = 3.14(729.28 mm²) = 2289.9392 mm²

The area is about 2289.94 mm², which rounds to 2290 mm².

Comment on pi

In the calculation here, we have used the required value of pi. If we use one that is more accurate, we find the area to be about 2291.10 mm².

the answer is the option b

the range is all real numbers

step-by-step explanation:

we know that

the absolute value parent function is equal to

see the attached figure to better understand the problem

so

a. it is v-shaped > is true

b. the range is all real numbers > is not true

because the range is the > [0,∞)

all real numbers greater than or equal to zero

c. it goes through the origin > is true

d. the domain is all real numbers > is true

step-by-step explanation:

its c or d   take a lucky guess my dude
