Use a portion of the circumference: pi x 2 x r x angle at centre =8xpix72/360 =8pi/5
Answer:
The total cost (in dollars) of p pens is C = 0.09 p
Step-by-step explanation:
The cost of each pen = 9 cents
Now, 1 cent = $0.01 cents
⇒ 9 cents = $0.09
So, the cost of 1 pen = $0.09
The number of pens purchased= p
Let the total cost of p pens = c
Also, the cost of p pens = p x ( Cost of 1 pen) = p ( $0.09) = 0.09 p
or, C = 0.09 p
Hence the total cost (in dollars) of p pens is C = 0.09 p.

What goes in goes out. This means none of the current is lost. So if 0.7amps+0.68amps+0.47amps = 1.85 amps comes in, then 1.85 amps goes out. So far we have 0.8 amps+0.55 amps going out= 1.35 amps. This means we need an additional 1.85-1.35amps going out= 0.5 amps for the third outgoing current. Cheers!
