The first option is the correct choice of answers.
An exterior angle is equal to the sum of the 2 non adjacent angles. In this case
100 = x + 70 Subtract 70
x = 100 - 70
x = 30
Answer:
A = 28.3 cubic inches; P = 20.1 inches
Step-by-step explanation:
<em>Looks like 3/4 of a full circle</em>
<em>The area of a circle is calculated with the formula: </em>
<em>Since the problem wants pi = 3.14, we use 3.14 instead of pi in the equation.</em>
<em>The radius is given as 3 inches</em>
Area =
cubic inches = 28.3 cubic inches
------------------------
<em>Perimeter is calculated with </em>
<em>.</em>
<em>But this is 3/4 of a circle with an additional two 3-inch sides</em>
Perimeter =
+ 2(3) = 14.1 + 6 = 20.1 inches
