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:
800 calories
Step-by-step explanation
Jace wants his total to be: 1,900
He consumed: 1,500
He burned: 400
How much is left: ?
Your equation would look like: 1900=1500-400+x
First step is to add like terms so: 1500-400= 1100
Now you subtract the calories Jace has gained with the total he wants to achieve: 1900-1100= 800
The amount he needs to gain is: x=800
1,100 is not aa viable solution because he want to keep his calory intake at 1,900, and 1,100 is the total for the calories he already consumed and burned while at the gym.
Hope this made sense!
