Question

find the perimeter of circle with diameter 7.5 cm ( π = 3.14) ​

Answer 1

$\huge \red{ \star \mathcal{Answer:-}}$

Perimeter of circle = Circumference of circle = 2πr

Diameter= 7.5 cm

Radius = 3.75 cm

Now,

$\bold{2\pi \: r = 2 \times 3.14 \times 3.75 = 23.62 \: cm}$

Answer 2

Step-by-step explanation:

diameter=7.5cm

radius=7.5/2=0.375m

perimeter=

$2\pi \: r$

2(3.14)(0.375)

2(11750)/100000

23500/100000

.235m/sq
