Answer:
2855.0
Step-by-step explanation:
there are several surface areas.
1. outside surface of the cylinder = circle circumference times height = 2*pi*r*height = 2*pi*14*14 = 1231.5
2. top and bottom of the cylinder = circle area times 2 = pi*r^2 * 2 = pi*14^2 *2 = also 1231.5
3. subtract the 2 cut out rectangles on the top and the bottom = 2* 6*14 = 168
4. add the areas of the inside walls of the cut out block.
there are 2 narrow rectangles = 2* 6*14 = 168
there are 2 squares = 2* 14*14 = 392
so, 1.+2.-3.+4. = 2855.0 (2855.00864...)
Answer:
I'm not sure what you're looking for so I'll give you everything that I can about that triangle. The angles of the triangle are 90°, 66° and 24°. The size of the triangle are 8.22, 3.66, and the hypotenuse is 9
Step-by-step explanation:
angle A and angle B are complementary angles meaning they add up to 90° since this is a right triangle so 66 + 24 = 90 angle A is 24°. Now to find the measures of The legs of this triangle will use trigonometry more specifically the sign function.
by the Pythagorean theorem
Answer:
square root of 3 = 1.7
square root of 6 = 2.5
square root of 9 = 3
square root of 12 = 3.5
Step-by-step explanation:
I think it’s false sorry if you get it wrong
The answer is 0=0
5(2)-(2+3)2=10+(-5)2
10-(2+3)2=10+(-5)2
10-10=10+(-5)2
0=10+(-5)2
0=10+-10
0=10-10
0=0
