Question

The circumference of a circle is 9.56cm find the length of the diameter give your answer rounded to 2dp

Answer 1

$\red{Question:}$

The circumference of a circle is = 9.56cm. Find the length of the diameter.

$\green {Answer:}$

$d = diameter$

$r = radius$

$2r = d$

$circumference = 2\pi r$

$circumference = 9.56cm$

$2\pi r = 9.56 \\ 2 \times \frac{22}{7} r = \frac{956}{100} \\ r = \frac{956}{100} \times \frac{7}{22} \times \frac{1}{2} \\ r = 1.52cm$

Now,

$d = 2r \\ d = 2 \times 1.52 \\ d = 3.04cm$

Diameter=3.04cm

Your Answer=d=3.04cm

Answer 2

$\sf ~ {\color{#6960EC}{Answer:-}}$

Circumference = 2$\pi$r = 9.56 cm

$\sf ~ 2\pi r = 9.56 \\\\ \sf ~2 \times \frac{22}{7} r = \frac{956}{100} \\\\ \sf ~r = \frac{956}{100} \times \frac{7}{22} \times \frac{1}{2} \\\\ \sf ~r = 1.52cm$

$\sf ~d = 2r \\\\ \sf ~d = 2 \times 1.52 \\\\ \sf ~d = 3.04cm$
