Answer:
3.75
Step-by-step explanation:
By Basic Proportionality Theorem:

The area of a circle is r^2pi and 2r = diameter. Thus r=diameter/2
r=6/2= 3 inches so the expression is 3^2*3.14 so I believe it's B
I'm not sure if this is a trick question but 1/2 because there are 2 options(yellow or blue) and one desired outcome(yellow)
Answer:
15.375
Step-by-step explanation:
Step-by-step explanation:
<y+60+58=180 (angle sum property)
<y+118=180
<y=180-118=62
<ACB+<ACD=180(degree of a line )
58+x=180
x=122
