Answer:

Step-by-step explanation:

r = d/2

d = 2 units

r = 2/2

r = 1

Area = pi * r^2

Area = 3.14 * 1^2

Area = 3.14 * 1

Area = 3.14

Answer:

π

Step-by-step explanation:

A=πr^2 is the formula to finding the area of a circle

A is area

r is the radius

2r=d

The diameter of a circle is twice as big as the radius so the radius is 1

1*1 is still 1 so we get

A=π1

which is just

A=π
