Frances read of an article in three minutes. How much of the article did she read each minute?
lions [1.4K]
Seems to be a typo:
If you meant to say just "an article" then it would be 1/3 of the article per minute.

If it is supposed to say "half of an article" he would have read 1/6 of the article per minute. Hope this helps!

The circumference of a circle is three pi inches. What is the area of the circle?
olga nikolaevna [1]

Answer:

Step-by-step explanation:

C=pi*3           Given

Generally C = 2*pi*r so we need to solve for r

3 pi = 2*pi * r   Divide by 2pi

3 pi/2pi = r

r = 1.5

Area = pi r^2

Area = pi * 1.5^2

Area = 2.25 pi

If you need a 1 number answer

Area = 7.065
