A) 78.5 cm

B) 4.7cm

C) 5.8cm

D) 23.0 cm

The answer to this would be B.) 4.7 cm

Step-by-step explanation:

Arch = (Angle/360)(2r)

= (45/360)(26)

= (0.125)(12)

=1.5

≈4.71cm (assuming = 3.14)

Since an arch of a circle is just part of the circumference, you just need to multiply the circumference by the measure of the arch's angle divided by 360 (the angle measure of a circle).

c: y > - 1/6x + 1

step-by-step explanation:

dashed line - meaning this < or > also not equal

solid line - meaning this < or > also equal

your answer is c because y > means up & it's shaded up, but y < means down

hope this ! : )
