Answer:
530.998cm^2
Step-by-step explanation:
General formula for the area of a circle is πr^2
And π is given to be 3.142
R is 13 cm
So let's apply the formula
Area=3.142×(13^2)
Area=3.142×169
Area=530.998cm^2
So the area of the circle is 530.998cm^2
Answer:
12 cm

Use the trigonometry triangles SOH CAH TOA
Sin= opposite/hypotenuse
Opposite= opposite the angle
Hypotenuse is the longest side
It would be $57 weekly, and when you multiply that by 4, you get $228/month
