Answer:
Kindly check explanation
Step-by-step explanation:
Given the question:
Find the error in the student's calculation. 2 cubed (2 minus 4) + 5 (3 minus 8). 2 cubed (negative 2) + 5 (5). 8 (negative 2) + 25. Negative 16 + 25. 9.
The student's error occurred here :
2 cubed (negative 2) + 5 (5)
(3 - 8) will give - 5 and not 5 as Witten by the student. The correct working is stated below :
2³(2 - 4) + 5(3 - 8)
Step 1:
8(-2) + 5(-5)
Step 2:
-16 + - 25
Step 3:
-41
Answer:
144
Step-by-step explanation:
First, do the top and bottom. The top is 2*4*3 or 24, and the bottom is 6*4 or 24.
Now, do the sides. It is a staircase that you can split into 6 2x2 blocks, or 6*4=24. Do the same with the other side to get 24 again.
Now for the front and back. This is 2*4*3 and 6*4 again, or 24 and 24.
Now you have 6 24's so just multiply these and get 144.

Answer:
B) 49,062.5 ft²
Step-by-step explanation:
The area of a circle can be found using the following equation:
A(c) = πr²
Note:
A(c) = Area of circle
π = pi = 3.14
r = radius
The diameter of the circle is given to you. To find the radius, simply divide the diameter by 2:
Diameter/2 = Radius
Radius = 250/2 = 125
Next, plug in 125 into the Area formula for circle for r:
A(c) = πr²
A(c) = π(125)²
A(c) = π * 15625
A(c) = 3.14 * 15625
A(c) ≈ 49062.5
B) 49,062.5 ft² is your answer.
