sorry i don't want the answer
Mid- Atlantic ridge is a part of
constructive plate boundary or divergent plate boundary. This linear feature
lies in the midst of a two tectonic plates that are apart from each other.
Active divergent plate boundaries usually take place in the middle of oceanic
plates then become mid-oceanic ridges. In fact that a Mid- Atlantic Ridge is
mainly an underwater feature, some of its segments have an altitude that
extends above sea level. Its boundary is situated along Atlantic Ocean's bottom
and areas of the world's longest mountain range.
Answer:
part A: 7.75 ft, part B: 48.69 ft
Explanation:
given a circle with diameter, D, 15.5 feet as shown below (<em>attached drawing</em>)
part A
radius, r = D/2
= 15.5/2
= 7.75 feet
= 7.75 (to the nearest hundredth)
part B
Circumference, C = 2πr
C = 2 × 22/7 × 7.75
C = 48.6947 feet
C = 48.69 (to the nearest hundredth)
note:
if you have 1234.5678, then
1 is Thousand
2 is Hundred
3 is Tens
4 is Unit
after the decimal, we have
5 is Tenth
6 is Hundredth (which is required in this question)
7 is thousandth
8 is Ten thousand etc
