The new cube will have 7 surfaces: 4 equal square sides, 2 square surface with a hole, and one hole surface.
Area (A1) of 4 square surfaces = 4*L*W = 4*4*4 = 64 cm^2
Area (A2) of the two surfaces wit a hole = 2(L*W - 2πd^2/4) = 2(4*4-π*2^2/4) = 25.72 cm^2
Area (A3) of the hole = πD*W = π*2*4 = 25.13 cm^2
Total surface area, A = A1+A2+A3 = 64+25.72+25.13 = 114.85 cm^2
Answer:
1. Circumference because the other two aren’t the correct answers and don’t sound like the correct answers.
2. 35 is the radius for the blue car
3. 20.1 is the radius for the green car
4. The difference between both cars radii is that one has a larger radius than the other

Answer:
-99, -90, 1/100, 10/100.
Step-by-step explanation:
To solve this, you need to know the formula to find the circumference of the circle. It is: C=2(pie)r.
C is what you are finding.
Pie is 3.14(you already got that).
R is the radius.
There is not enough information to solve your problem, but I hoped the equation helped!
Answer: Choice A) y - 10 = 2(x - 3)
============================================================
Explanation:
We can rule out choices C and D because this diagonal line has a positive slope (as it moves uphill when moving to the right).
So m = 2 must be the slope.
---------
Recall that
y - y1 = m(x - x1)
represents the point slope form of a linear equation.
The point shown on this graph is (3,10) meaning that x1 = 3 and y1 = 10 pair up together.
So,
y - y1 = m(x - x1)
y - 10 = 2(x - 3)
which points to <u>choice A</u> as the final answer
