Answer:

f = 8

Step-by-step explanation:

  1. Apply the distributed property, so it now looks like this: 2f - 10 = 6
  2. Add 10 to each side, so it now looks like this: 2f = 16
  3. Divide each side by 2 to cancel out the 2 next to f. It should now look like this: f = 8

I hope this helps!

Find the perimeter and total area of the composite shape shown below. All measurements are given in inches. Use pi equals 3.14 i
seropon [69]

Answer:

Perimeter = 65.12 in

Area = 292.48 in^2

which agrees with the second answer choice

Step-by-step explanation:

The perimeter is going to be the addition of the sides of the rectangle external to the composite figure ( 12 + 16 + 12 = 40) PLUS the length of half of the circumference or radius 8 inches  (which is pi * radius = 3.14 * 8 = 25.12 in)

Then the total perimeter is:

Perimeter = 40 in + 25.12 in = 65.12 in

The are is going to be the area of the rectangle (12 * 16 = 192 square inches) PLUS the area of the semicircle of radius 8 in (pi *radius^2 /2 = 100.48 square inches).

Therefore the total area is:

Area = 192 + 100.48  = 292.48 in^2
