Answer:
87.92 in²
Step-by-step explanation:
pi × (R² - r²) = area
Where R is the radius of the outer circle and r of the inner circle.
Since C = 2pi×r
37.68 = 2×3.14×r
r = 6 in
R = 6 + 2 = 8 in
Therefore,
pi × (R² - r²) = area
Area = 3.14 (8² - 6²)
= 87.92 in²
Answer:
AB = 4
BC = 4
AC = 8
Step-by-step explanation:
Given, B is the midpoint of AC which means it divided the AC into two equal parts. Using this information we can write the following equation:
5x - 6 = 2x add 6 to both sides
5x = 2x + 6 subtract 2x from both sides
3x = 6 divide both sides by 3
x = 2 to find the length of AB, AC, and BC replace x with 2
AB = 5*2 - 6
BC = 2*2
AC = 8 (sum of AB and BC)
<h3>A glass of lemonade took 2 1/2 scoops of sugar to make in it. If you wanted to make 3 glasses how many scoops of sugar would you need</h3>
<h3>
</h3>
<h3>First,</h3><h3>Change the fraction to decimal. 2½=2.5</h3><h3 /><h3>Second,</h3><h3>Simply Multiply it by 3! 2.5×3=7.5</h3>
<h3>Therefore, you need 7.5 (7½) scoop of sugar to make 3 glasses of lemonade.</h3>
87+87+81+86+89+83+89= 602. Divided by 7 because that’s how many numbers there were is 86 and that is your mean/average.
Your answer would come down to be 3a^2/b
