Answer:
11 sq.ft
Step-by-step explanation:
∅= 80×π/180= 4π/9
area= 1/2 × r²× ∅
= 1/2 × 16 × ∅
= 8∅
=8×(4π/9)
= 32π/9
= 11.17 ~11
Hello!
To find the area, we use the formula A=pir², where pi=3.14 and r= the radius.
To solve, we find half of the diameter, which is the radius. Half of 53 is 26.5. We square this number and then multiply it by pi. 26.5·26.5=702.25. Now we multiply by pi. 702.25·3.14=2,205.065.
Our final answer is about 2,205.1 cm².
I hope this helps!

Answer:
True; about 120° CCW rotation about Q
Step-by-step explanation:
Triangle A'B'C' appears to be congruent to triangle ABC and about the same distance from point Q. The angle of rotation from ABC to A'B'C' appears to be about 120° counterclockwise when measured using a geometry program.
Triangle A'B'C' is the image of triangle ABC under rotation about 120° CCW about point Q.

<em>Additional comment</em>
If choices of rotation angle are ±135° or ±165°, the best choice would be ...
135°
The sides of the box are 12in by 12in by 30in.
The interior diagonal =[12^2+12^2+30^2]0.5
=[144+144+900]^0.5
=1188^0.5
The final answer is 34.47in.
My deepest apology if this is not what you meant.
= 34.47in.
