Answer:

The percentage difference between the two methods is 2.95%.

Step-by-step explanation:

The percentage difference is the difference between two values divided by the average of the two values. Shown as a percentage.

The difference means to subtract one value from another and the average is given by

average=\frac{first \:value+second \:value}{2}

Given

d_1 = 2.75 \:{g/cm^3}\\d_2 = 2.67 \:{g/cm^3}

The difference is 2.75-2.67=0.08

The average is \frac{2.75+2.67}{2} =2.71

And the percentage difference is

\frac{0.08}{2.71} \times100\%=2.95\%

The sum of the measures of the interior angles of a convex polygon is 3960°.
scZoUnD [109]

Step-by-step explanation:

The sum of the interior angles of a convex regular polygon is 180 times (n-2), where n is the number of sides. Since we already know the sum, we can write 3,960 = 180(n-2). If you solve for n in this equation, you will have the number of sides.
