The area of a circle can be found by the formula A=pi*r^2. Pi equals 3.14 so multiply that by 13^2. 13^2 equals 169. So 3.14 * 169 = 530.66 cm^2 and that rounded is B) 530.7cm^2

It would be B (530.7) because if you do 3.14 x 13 x 13 (Or to the second power) Then you get 530.66, the round to the nearest tenths

sweet-ann [11.9K]

Answer:

if your 4.5-year-old sister was asked to Put the bunny on the blanket on the shelf, she may or may not  if your 4.5-year-old sister was asked to Put the bunny on the blanket on the shelf. But,the chance is very likely less than 50%.

Step-by-step explanation:

If your 4.5-year-old sister was asked to Put the bunny on the blanket on the shelf, the chance that she might follow the instructions she receives is less 50 percent. In other words:

                                      Chance < 50%

The reason is that children at this age may have challenging time figuring out the subject when you may instruct certain things to do, as the sentences could be tricky for the children to decode the meaning.  

So,  if your 4.5-year-old sister was asked to Put the bunny on the blanket on the shelf, she may or may not  if your 4.5-year-old sister was asked to Put the bunny on the blanket on the shelf. But,the chance is very likely less than 50%.
