DE equals 7.5 centimeters. You divide 5 by 2, line CA by CB, and get 2.5 which is the zoom factor. Then multiply 3 by 2.5 to get DE.
Sum of triangle angles = 180
smallest angle = x
second angle = 3x
third angle = x +35
180 = x + 3x + x + 35
145 = 5x
x = 29 is the smallest
the second is 87
the third is 64
Answer:
The answer is B-452.4
Step-by-step explanation:
The formula for volume of a cylinder is V= πr^2h
so you would do 3.14 times 6 squared times 4
6 squared is 36 times 4 equals 144. Then you multiply that by pi, or 3.14 and you get 452.16 round to the nearest tenth and get 452.2
Hope this helps!
Answer:
37.68 units^2
Step-by-step explanation:
Area of whole circle: 50.24 units^2
Area of 1/4 of it: 50.24/4=12.56
50.24-12.56=Area of remaining
Area of remaining=37.68 units^2
