Question

The diameter of a circle is 6.4 in.

What is the approximate area of the circle?

Use 3.14 for π .


A.) 20.096 in²

B.) 32.154 in²

C.) 128.614 in²

D.) I don't know.

Answer 1

B. 32.154 in²

Explanation:

A= 3.14 * r^2

A= 3.14 * 3.2^2

A= 32.154

Answer 2

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
