Question

The diameter of a circle is 4 m. Find the circumference to the nearest tenth.

Answer 1

Circumference equals 2 times pi times radius.

Diameter of 4m means the radius is 2m

2 x 3.14 x 2 = 12.56637

12.6 is your answer

Answer 2

Answer :

$\bf \large 10 \: m$

Step by step explanation :

Given that :

• The diameter of a circle is 4 m.

to find :

• Find the circumference to the nearest tenth.

formulas used :

• circumference = π × Diameter

where,

• π = 22/7
• Diameter = 4 m

explanation :

⟼ c = πd

⟼ c = 22/7 × 4 m

⟼ c = 88/7 m

⟼ c = 12•57 m.

Round to the nearest tenth :

⟼ c = 12•57 m

⟼ c = 10 m.

∴ circle circumference is 10 m.
