Answer:
Rotation of 90° counterclockwise about the origin
Answer:
Step-by-step explanation:
Actually, you can't. You could multiply the numerator and denominator of each 4/3 and 3/3 by 5, obtaining:
5(4) 5(3)
------ and --------
5(3) 5(3)
but this result has little practical value. 4/3 and 3/3 could be combined immediately, obtaining 7/3, if that's what you want to do, as the fractions already have the same denominator (3).
The base of a cone is a circle.
The area of a circle is

.
Thus, the area of the base of a cone

.
The derivation of the formula for the area of a circle involves a bit of calculus, but if you'd like, I can walk you through it.

The answer is A because you would do 79 x 0.05 which equals 3.95 . So you subtract 3.95 from 79 which is 75.05 minus 50 equal to 25.05
