Question

PLEASE SOLVE IT WITH THE RIGHT WAY VERY URGENT

calculate the diameter of each circle whose radii are given below:-

a) 4.2cm
b) 19.5cm
c)100m
d)26.4cm

please please answer me fast​

Answer 1

diameter

a. 8.4

b. 39

c. 200

d. 52.8

Answer 2

Answer

1. r = 4.2 cm

d = 2r

d = 2*4.2

d = 8.4 cm

2. r = 19.5

d = 2r

d = 2*19.5

d = 39 cm

3. r = 100m

here the value of the radii is in m

so we have to first convert it into cm

1 meter = 100 centimeters

∴ 100 meter = 10,000 centimeters

so r = 10,000 cm

d = 2r

d = 2*10,000

d = 20,000 cm

4. r = 26.4 cm

d = 2r

d = 2*26.4

d = 52.8 cm

hope this helps you!!!!
