2(pi)r = 9.4in
(pi)r = 4.7in
3.14r = 4.7in
r = 1.497in
Surface Area Of a Sphere = 4(pi)r^2 = [4(3.14)(1.497)^2]in^2 = 28.147in^2 = 28in^2
Volume Of a Sphere = 4/3(pi)r^3 = [4/3(3.14)(1.497)^3]in^3 =14.05in^3 = 14in^3
Answer is 32cm^2. See attachment for the working.
What you do, is you take 13 and multiply it by 10.
So let's do it!
13x10=130
Therefore we get the answer, which is 130.
Well, it depends on what the tenth is. A tenth is a place value, not a number. 0.1, goes in 5 50 times. 0.2 goes in 25 times. 0.3 goes in 16.667 times. 0.4 goes in 12.5 times. 0.5 goes in 10 times, 0.6 goes in 8 .33333333...(Repeating) 0.7 goes in 7.142 times. 0.8 goes in 6.25 times. 0.9 goes in 5.556.
First, you would add 11x to both sides, because you are trying to separate the variable pieces and the constants (integers).
If performed correctly, you would get the equation
7x-5=6
Then, you would add 5 to both sides, to get the 7x alone.
This results in the equation 7x=11
Then, to get x alone, without a coefficient, you would need to divide both sides by 7.
x=11/7
