<h2>Answer:</h2><h3>104771 rounded to 1 significant figure is 100000</h3><h2>Step-by-step explanation:</h2><h3>To round any number to 1 significant figure you have to identify the first non-zero digit. </h3><h3>For 104771 that number would be 1 because it is the first non-zero digit. Then you can draw a vertical line behind the number like this. 1:04771</h3><h3>Then, you look at the next number that is behind the line. If the number is more than 5, you increase the previous digit by 1. If the number is 4 or less, you keep the previous digit the same. In this case, the number is less than 4 so we keep the digit the same. This gives us 100000 (1 significant figure)</h3>

Answer:
4.76cm
Step-by-step explanation:
Given data
circumference= 15cm
The expression for circumference is
C= 2πr
substitute and solve for r
15= 2*3.14*r
r= 15/ 2*3.14
r=15/ 6.28
r= 2.38 cm
Hence the diameter is
D= 2r
D= 2*2.38
D=4.76cm
