Answer:
Diameter of a circle = 1.6 Cm
Step-by-step explanation:
Given:
Distance between first and third coins = 3.2 cm
Find:
Diameter of the coins = ?
Computation:
Number of circle = 3
In the given figure,distance between the first and third coins is 3.2 cm.
So,
Distance = 1st circle radius + 2nd circle diameter + 3rd circle radius
Distance = 1st circle radius + 2 (radius) + 3rd circle radius
Distance = R + 2R + R
3.2 Cm = 4 R
Radius = 0.8 Cm
Diameter of a circle = 2 × radius
Diameter of a circle = 2 × 0.8
Diameter of a circle = 1.6 Cm
Answer:
it take 1/7 km in 1 hour then,
1 km it take 7 hours
so, it cover 5 km in 35 hours
1/7 km ------- 1 hour
1km ------- 7 hour
5km -------( 5*7) == 35 hours

Answer:
b=0
Step-by-step explanation:
y=mx+b
(0,0) means x=0 and y=o
m=2
Make b the subject of formula
b=y-mx
b=0-2(0)
b=0-0
b=0
Therefore,0=2(0)+0
=0
Therefore the equation of the slope is 0
