1. 10 in Radius: Diameter Circumference Area:​

The diameter is 20 units, the circumference is or about 62.83, and the area is or about 314.16

Step-by-step explanation:

To get the diameter, you can mutiply the radius by 2. (10*2= 20)

To get the circumference, you can use the equation , substituting r for the radius. For an exact answer, use pi. For an approximate, do only 2 times the radius and append pi to the answer ().

To get the area, you can use the equation , substituting r for the radius. For an exact answer, use pi. For an approximate, do only the radius squared ().

step-by-step explanation:

134.6 us dollars

step-by-step explanation:

1 us dollar = 1.33 canadian dollars

so, 150 us dollars = 150 × 1.33 = $199.5.

in canada, the money mitchell spent = 20 canadian dollars.

remaining canadian dollars with him = 199.5 - 20 = 179.5.

after mitchell returned to us, he exchanged the remaining canadian dollars to us dollars.

179.5 canadian dollars = 179.5 × 0.75 = 134.6 us dollars.
