The diameter of a circle is 4 yards. What is the circle's area?
Use 3.14 for n.
square yards

Area of a circle formula: area = pi x r^2

R is the radius which is 1/2 the diameter.

The diameter is 4 yards so the radius is 4/2 = 2 yards.

Area = 3.14 x 2^2

Area = 12.56 square yards.

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
