A = πr^2 where r= diameter/2 = 6 in
A = 6*6π in
A = 36π square inches or approximately <span>113.04 square inches

A triangle has two angles with measures of 90 and 20 degrees joined by a side with a length of 12 centimeters.
vichka [17]

Answer:  C

Step-by-step explanation:

We know that A and D will not be the correct answers. For A, it's only one 90 angles, but the questions said that has two angles. For D, it's two angles  : 90 and 12, but in the question, 12 is the length, not the angle.

The correct answer is C.
