The diameter of circle is 1.018 mm.

Step-by-step explanation:

Given,

Circumference of circle = 3.2 mm

We know that;

Circumference = 2πr

$3.2=2\pi r\\$

Putting π=22/7

$3.2=2*\frac{22}{7}*r\\3.2=\frac{44}{7}r$

Multiplying both sides by 7/44

$\frac{7}{44}*3.2=\frac{7}{44}*\frac{44}{7}r\\\\\frac{22.4}{44}=r\\\\r=0.509$

Diameter = 2r

Diameter = 2*0.509

Diameter = 1.018 mm

The diameter of circle is 1.018 mm.

Harper's house is 30 feet wide and 45 feet long. On a scale drawing, the house is 4 inches wide and 6 inches long, and Harper's

Vsevolod [243]

The scale factor is 7.5 because if you divide 30 by 4 and 45 by 6, it is 7.5.
So to find the actual measurement of Harper's bedroom, you multiply 1.2 by 7.5, that would be 9 feet wide, and 1.6 by 7.5, that would be 12 feet long.

9 feet wide, 12 feet long

Oksi-84 [34.3K]

Given that,

The length of ribbon= 36 inch

We know, if Shelia wants to divide the ribbon in 5 equal parts, she needs to divide the length of the ribbon by 5.

So,

The length of the 5 equal parts of the ribbon= 36/5= 7.2 inch

But Shelia got each pieces length equals to 7 inches.

So, There is an error of (7.2-7) 0.2 inches in her calculation.
