Answer:
1 11/21
Step-by-step explanation:
In order to convert 32/21 to mixed number, you follow these steps:
Divide the numerator by the denominator
32 ÷ 21 = 1 with a remainder of 11
Write down the whole number 1 and then write down the remainder as new numerator (11) above the denominator (21), As below:
1 11/21
We know that
[length of a circumference]=2*pi*r
diameter=10 cm
r=10/2-----> 5 cm
[length of a circumference]=2*pi*5-----> 10*pi cm
if 360° (full circle) has a length of -----------> 10*pi cm
X°---------------------------> pi cm
X=pi*360/10*pi------> 36°
the answer is 36°
