Calculate the radius using the circumference given in the figure:
To solve this problem, we'll follow these steps:
Now, let's work through each step:
Step 1: Apply the formula for radius:
Step 2: Plug the value of as per approximation or implication for this problem solving.
Step 3: Assuming we process the calculations from the less seen cues due to approximation indicating to the result — moving directly by computation logic:
Step 4: Calculate as expressed where circumference whole solution breakthrough confirms approximate value.
The calculated radius is .
Therefore, the answer is .
0.009
\( r=2 \)
Calculate the circumference.
Because the circumference formula is , not ! The 2 comes from the fact that radius is half the diameter, and we need to account for this in our calculation.
For most problems, 3.14 gives accurate enough results. However, using the π button on your calculator will give more precise answers. Check what your teacher prefers!
Perfect! When you see something like , just substitute: . The π values cancel out nicely!
Remember that very small circles exist! A circumference of 0.05652 units means you have a tiny circle - maybe measured in millimeters or smaller units. The math is still correct!
Absolutely! Use with your calculated radius. If you get back to the original circumference (within rounding), your answer is correct!
