If 9 is the radius and 20 is the height then it would be 5089.4 cm^3
The complement of 31° is the angle that when added to 31° forms a right angle (90° ).
Answer:
d. 0.133
Step-by-step explanation:
-Standard error is calculated using the formula:
#We substitute the given values in the formula to solve for E:
Hence, the standard error is 0.133 and the correct option is d
<h3>
Answer: SAS</h3>
=================================
How to get this answer:
We're told that AD = BC, so that is one pair of sides that are congruent. This forms the first "S" in "SAS"
The "A" refers to the congruent angles, which happen to be angle DAB and angle CBA, both are 90 degrees
The second "S" in "SAS" is the second pair of congruent sides. Those two sides are the overlapping shared side of AB. It might help to peel the two triangles apart to get a better look.
Note how the angles are between the two pairs of sides mentioned.
