What is 4 ÷ 1 1/8 please tell me ​
kogti [31]

When dividing fractions, theres this thing you do call "keep, change, flip"

You keep the first fraction the same, change the division to a multiplication, and change the fraction to have the numbers flipped.

4 = 4/1

1 1/8 = 9/8

4/1 * 8/9 = 32/9

32/9 = 3 5/9

3 5/9 is the final answer

The area of a circle is 28.26 square centimeters. What is its diameter (use 3.14 for ð)?
horsena [70]
Area for circle is  πr² so πr² =28.26 and we can sub 3.14 as pi
3.14*r²=28.26 we can divide by 3.14 to get r² on it's own
r²=28.26/3.14
then we root both sides to get r on it's own
28.26/3.14=9 √9=3
and the diameter is double the radius 3*2=6 so the diameter is 6
