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:
B. 32.154 in²
Step-by-step explanation:
A= 3.14 * r^2
A= 3.14 * 3.2^2
A= 32.154
