Answer:
Power is the rate at which energy is put into, or taken out of, a system. For example, a 500 Watt halogen light uses 500 Joules of energy every second.
There are two common units of power, the Watt and the Horsepower. This page will help you to convert between them.
Step-by-step explanation:
5/1 x 6 4/15
5/1 x 94/15
Answer: 94/3 or 31 1/3
A = 0.366666 ... = 0.3(6)
10a = 3.(6)
100 a = 36.(6)
100a - 10a = 36.(6) - 3.(6)
90a = 33
a=33/90=11/30
oh wait lol i didnt notice it was from 2017
Answer:
C = 14*pi cm
Step-by-step explanation:
The area of a circle is given by A = pi * r^2
We know the area is 49 pi
49 pi = pi r^2
Divide each side by pi
49 pi/pi = pi/pi r^2
49 = r^2
Take the square root of each side
sqrt(49) = sqrt(r^2)
7 = r
Now we need to find the circumference
C = 2*pi*r
C = 2 *pi *(7)
C = 14*pi cm
