Answer :
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,
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.
