The formula to find the surface area of a circle is: pi x radius², so if we square the radius the answer would be 25, then we multiply that by 3.14 and the answer would be around 78.5, so the answer is 78.5.
Answer:
radius = 6
Step-by-step explanation:
The equation of a circle centred at the origin is
x² + y² = r² ←r is the radius
x² + y² = 36 ← is in this form
with r² = 36 ⇒ r =
= 6
Answer:1564cm cube
Step-by-step explanation: v=
r2h
v=22/7*6*6*14=1564.containter b volume of water is the total volume in container a so you just have to find container a volume
The answer is 2 and over it is 3
