Answer:
47.065
Step-by-step explanation:
The formula for area of a circle is A = πr^2
Since the diameter is double the radius, divide 3 in half to get 1.5.
Then plug your numbers into the equation and remember to start with exponents.
3.14 x 1.5^2 or 3.14 x (1.5 x 1.5)
Answer:
7.07 cm
Step-by-step explanation:
Area of a circle = πr²
{diameter = 3 cm ; radius = 3/2 = 1.5 cm}
πr²
= 3.14 x (1.5)²
=3.14 x 2.25
= 7.07 cm (approx)
