Answer:
28.26
Step-by-step explanation:
For this, we can simply use the pi times r squared because we have the radius.
simplify pi to 3.14, so we can do 3.14 times 3 squared.
we get 9x 3.14, which is 28.26.
C)
It’s far off from most of the points
Answer:
449/20 or 22 9/20
Step-by-step explanation:
Change them to mixed numbers.
55 x 5 = 275 + 1 = 276
32 x 4 = 128 + 3 = 131
Then, convert them to a common denominator.
276 x 4 = 1104
131 x 5 = 655
1104 - 655 = 449
449/20
