Answer:
90 units
Step-by-step explanation:
circumference C = 2
r
taking
as 3.
C = 2 × 3 × 15
(15 is the radius of the circle)
C = 90 units
You would use Pythagorean theorem to help u out if u have 2 sides u should be able to do it.
Sydney has 10 because 30 is 3 times as many as 10 and then the extra 6 is the one you added when it says 6 more than three times
Answer:
The value of currents are
,
and
.
Step-by-step explanation:
The Ohm's law states that
It is given that the V₁=3V and V₂=4V.
In a parallel circuit:
→ Voltage is same in each component
→ Sum of the currents equals to the total current that flows.
.... (1)
Equation for first loop is,
..... (2)
Equation for second loop is,
..... (3)
On solving (1), (2) and (3) we get
Therefore the value of currents are
,
and
.
