Step 1: Write out the formula

Step 2: Write out the given values and substitute them into the formula

Therefore,

Hence, the area in terms of pi is

The last choice is the correct answer
Since 40%=40/100=4/10, we can divide 11 by 10 and multiply that by 4 to get the weight gained, which is 1.1*4=4.4. The weight gained paired with the starting weight = 10+4.4=14.4
The factored form of this expression would be :
(k-3h)(k+3h).
The answer would be B. You would need to keep the first fraction, change to multiplication, and flip the second fraction and multiply across.
Answer:
16
Step-by-step explanation:
Given
C=2r and r=8
So
C=2×8 (as r=8)
C=16 (ans)
