Step-by-step explanation:
just me doing work vvvvv
65 + 45.5 = 110.5
---
7 x 6.5
45.5
<span>rational number between 5.2 and 5.5 is 53/10 (cause 53/10 = 5.3)
</span>irrational number between 5.2 and 5.5 is √29 (cause <span>√29 = 5.385164....)</span>
The radius of the circle is 3 cm.
<u>Step-by-step explanation:</u>
Refer the attached diagram, the circle with centre O. In that given, AB is tangent given as 4 cm and distance of point from the circle, OA = 5 cm
As AB is tangent, OB (radius of circle) is perpendicular to AB (tangent at any point of circle). Therefore the angle of OBA is 90 degree.
Also, triangle OAB is a right angled triangle (refer attached diagram). By using Pythagoras theorem in right angled triangle,


Substitute the given values in the above expression, we get


Taking square root on both side, we get
Radius of the circle, OB = 3 cm
Answer:
The first one, 4:6
Step-by-step explanation:
