Question

if circumference is 44cm what is the radius diameter and area​

Answer 1

Answer:

2πr = 44 cm.

2× 22/7 × r = 44 cm.

r = 44× 7 / 44 cm.

r = 7 cm.

Hence Radius = 7 cm.

Now Diameter = 2 times of Radius

Diameter = 7 × 2 = 14 cm.

Hence Diameter = 14 cm.

Now area of circle = πr² cm ²

Area = 22/7 × 7 × 7 = 154 cm ²

Hence Area = 154 cm ²

Answer 2

Answer:

$\huge\tt\colorbox{black}{\red{❥answer࿐}}$

Circumference of circle = 2πr

$2 \times \frac{22}{7} \times r = 44 \\ r = \frac{44 \times 7}{2 \times 22} = 7cm \\ radius \: of \: circle \: = 7 cm$

$Area \: of \: circle \: =\pi r ^{2} \\ = \frac{22 }{7} \times 7 \times 7 \\ = 154 \: cm ^{2}$

Circumference of circle = πd

πd = 44

$\frac{22}{7} \times d = 44 \\ d = \frac{44 \times 7}{22} \\ d = 14 \: cm \\ diameter \: of \: circle \: = 14 \: cm$
