Answer:
C = 14π cm
Step-by-step explanation:
C = πd
or
C = 2πr
Simply use the 1st equation and plug in the diameter to find you answer.
The second attachment I solved in your another question.You may refer to that.
#1
Apply Pythagorean theorem
x²=10²-6²
X=1
To solve this you start by adding like terms on the left side and doing the distributive property and adding like terms on the right. This would get you
4x+7=3x+8
Then you minus 3x on both sides getting
x+7=8
Then subtract 7 from both sides getting x=1.
Let the number of hours she spent in baby- sitting is x
and the number of hours she spent in music lessons is y.
Now, we have been given that she worked a total of 18 hours. Hence, we have
And she made $139. Thus, we have
Substituting the value of y from equation 1 in 2, we get
Therefore, she spent 11 hours in baby-sitting.
