Answer:
B. 50.24
Step-by-step explanation:
to find the area of a circle you need to use the formula
a=r²π
since the radius is 4 we put that into the equation, lets use 3.14 for pi
a=(4)²×3.14
always do exponents first
a=16×3.14
a=50.24
Y=4x
Your answer will be x in relation to y. In this case, x goes in to y 4 times.
