Answer:
diameter = 16cm, circumference ≈ 50.27
Step-by-step explanation:
The radius is 8 centimeters, so the diameter should be twice of that because the radius is the distance from the middle of the circle to the edge while the diameter is from edge to edge passing through the middle of the circle. Therefore,
8 · 2 = 16cm
The equation for the circumference of a circle is 2πr. In this case, because nothing else is specified about π, we use 3.14. So,
2 · 3.14 · 8 ≈ 50.27
Hope this helped! Have a great day. ^^
Answer:
The scale factor is 3
Step-by-step explanation:
The width of A is 1, the width of B is 3
the length of A is 3, the length of B is 9 so the scale factor from A to B is 3
It means that the two line segments, EF and GH, are A, parallel.
The symbol between the segments (ll) is of two parallel lines, so it's stating that the segments are parallel.
