Question

If a circle has a radius of 7/4 cm, what is the diameter?

Responses

a) 3 1/2 cm


b) 7/8 cm


c) 1 3/4 cm


d) 2 1/4 cm

Answer 1

Explanation:

Answer 2

Option A)
`3\frac {1}{2}`

Explanation:

In order to find the diameter you need to multiply the radius x 2

Over here the radius is given as 7/4cm

But the diameter is

`(7)/(4) X(2)/(1)` =
`(7)/(2)`

And when we simply the mixed fractions we only get one possible answer

which is
`3(1)/(2) = (7)/(2)` Option A)
