Question

circumference of a circle whose diameter is 1.5 m.
with formula​

Answer 1

$\huge\bold\red{Answer}$

Answer is 33 m

Given,

Diameter (D) = 1.5 m

To find :

Circumference of circle

Solution :

We know that,

Circumference of circle with diameter = πd

⇒ 22/7 × 1.5

⇒ 4.714

Hence, circumference of circle is 4.714 meter (m)

Answer 2

$\huge\sf\underline\purple{Solution:-}$

Given Diameter 1.5m

Radius 1.5/2 = 0.75

FORMULAE:

Circumference of circle interms of radius 2πr

Circumference of circle interms of diameter πd

_____________________

METHOD-1Circumference of a circle in terms of radius = 2πr

2×22/7×0.75=4.714 m

METHOD-2Circumference of circle in terms is πd

22/7×0.75 = 4.714

Here we can solve by two methods Directly by diamter we can solve or we can convert into radius also we can solve....

So final answer is 4. 714 m
