Sorry my answer was wrong so I just edited it sorry
2.50+2.50+2.50+ half of 2.50 which is 1.25 = 7.50+1.25=8.75 i think
The current when the resistance is 10 ohms is 24 amps
<h3>What are variations?</h3>
Variations are simply data that change in values (i.e. not constant)
<h3>Types of variation</h3>
The types of variations are:
- Direct variation
- Inverse variation
- Joint variation
- Combine variation
From the complete question (see attachment), we have the following highlights
- The variation is an inverse variation
- When current (I) is 30 amps, the resistance (R) is 8 ohms
An inverse variation is represented as:

Where k represents the constant of variation.
The above equation can be rewritten as:

So, we have:


When the resistance is 10 ohms, we have:

Divide both sides by 10

Rewrite the above equation as:

Hence, the current when the resistance is 10 ohms is 24 amps

HOPE THIS HELPS YOU..... :)
The calculation for circumference is 2πr or 2 × π (pi=3.14) × radius of a circle
Since the diameter of this circle is 7cm, and the radius is half of the diameter, 7 ÷ 2 = 3.5
So, 2×3.14(π)×3.5=21.98
