Answer:
Area of whole circle, i.e. 360 degrees = π(8.91)(8.91) = 79.3881 sq. cm
Area of 1 degree = 0.2205225 sq.cm.
Area of 81 degrees = 17.8623225 sq.cm.
Calculus! First one I've seen here! Take the derivative of the volume of a cube. Volume is V = s^3, dV = 3s^2 ds when s = 10 and ds = 3. I think you used x. Anyway, in the derivative fill in the s with a 10 and the ds (rate of change) is 3. So dV = 3(10)^2 * 3
dV = 600 cm per second
Answer:
Her next step would be to add 12 to both sides of the equation
Step-by-step explanation:
Which would make the equation 4x=28
Then you divide both sides by 4 giving you x=7
There is no choice on your list that must represent an odd integer.
If 'z' is an even integer, then (z-1) and (z+1) must both be odd integers.
Converting decimals into fractions is simple, all you have to do is think about the number, for example .25, if you look at it you realize it's 1/4 of 1, so it's naturally 1/4, you do this with all of them
