Answer:
1. 18.84 in
2. 56.52 cm
Step-by-step explanation:
The circumference of a circle is the distance around the circle. Its found using the formula C = πd or C=2πr. The variable d represents the diameter or the distance from one edge of the circle to the other through the cent. The variable r represents the radius of a circle or the distance from one edge to the center. Use the formula by substituting a diameter or radius then simplify.
1. C = πd = π(6) = 3.14(6) = 18.84 in
2. C = 2πr = 2(3.14)(9) = 56.52 cm
Your answer to this is 200
30-4 (2+5) = 2
30-4(7)=2
30-28=2
I think the answer's C: $7000/$8000
That's a surprisingly easy question for high school
Answer:
Step-by-step explanation:
Given Data,
Q=23000 J
c=4.184 J/g °c
Δt= 68 °c
m=?
By using this equation,
Q=mcΔt
