To answer this, let's first describe the two areas and obtain the pertinent dimensions from them.
The area of the square hole is 5 cm^2. Since A = s^2, where s is the length of a side of the square, s = +√5 in this situation. +√5 is approx. 2.24 cm.
The area of the round peg is 5 cm^2 also, but the area is calculated using a different formula: A = πr^2, where r is the radius of the circle. Solving for r^2, we get:
r^2 = A/π. Here, r^2 = (5 cm^2)/π = 5π, so that:
r = +√(5π). This is approx. 3.96 cm, and so the diameter is twice that, or 7.93 cm.
So there's plenty of room for the round peg to enter the square hole, but not the other way around!
We want to find total to red
total just add
14+8+12=14+20=34
red=8
total to red=34:8 or 34/8=17/4=17:4
Answer:
166.59 cm³ (approx.)
Step-by-step explanation:
Greetings!
Option C would be correct.
3 + 4 + 5 = 13 therefore, C is the best answer.
Hope this helps!
