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:
Yup if you have 8+8=14 then 8+8-1=-1
Value of x is 9 and measure of each side is 35 units.
<u>SOLUTION:
</u>
Given, Triangle QRS is an equilateral triangle.
QR is seventeen more than twice x, 
RS is 19 less than six times x, 
And QS is one less four times x, 
We have to find x and measure of each side.
Now, we know that, sides of equilateral triangle are equal,
Then 
So, value of x is 9.

Hence, value of x is 9 and measure of each side is 35.

Answer:
8 units
Step-by-step explanation:
Displacement is the area under the velocity curve. The area of interest is in the shape of a trapezoid, so we can use the formula ...
A = (1/2)(b1 +b2)h
to find the area.
Here, b1=3, b2=1, h=4, so the area is ...
A = (1/2)(3 +1)(4) = 8
The displacement is 8 units in the time from t=1 to t=4.
