Find the circumference

Mathematics
1 answer:
lbvjy [14]1 year ago
6 0

Answer:

56.52m is the circumference. The area is 254.34m^{2}

Step-by-step explanation:

The equation for the circumference of a circle is c=2πr with r being the radius. So 2(3.14)(9)=56.52m. The area equation for a circle is A=πr^{2} so it would be (3.14)(9)^2 or (3.14)(81) which equals 254.34m^{2}

26 out of 48 books are small. What percentage of the books are small?
Paraphin [41]

Answer:

54.16%

Step-by-step explanation:

The percentage of books that are some is 54.16 %

In order to find that answer you would have to calculate the total number of small books (26) over the total number of all of the books (48).

The equation would be 26/48=0.5416 however Multiply that answer by 100 and you would get 54.16% and if you want to round to the nearest whole number it would just be 54%
