Question

The diameter of a circle is 6.4 in.

Answer 1

Answer: B.) 32.154 in²

Step-by-step explanation: divide 6.4 by 2 to get the radius then it is 3.2

then the formula to find the area of a circle is Area = πr²

π = 3.14

so... Area= 3.14x3.2²

                = 3.14x10.24

                = 32.1536

then when u estimate the value u get 32.154 in²

Answer 2

Answer:

B. 32.154 in²

Step-by-step explanation:

A= 3.14 * r^2

A= 3.14 * 3.2^2

A= 32.154
