Find the circumference of a circle with diameter, d = 4.7m. Give your

1.	Find the circumference of a circle with diameter, d = 4.7m. Give your answer rounded to 2 DP.
Answer» Step-by-step explanation: we can answer this by using the FORMULA for circumference of a circle, i.e, 2πr or πd where r = radius and d = diameter. therefore, circumference will be πd because d is given as 4.7 m. we can use EITHER VALUES for π, 22/7 or 3.14, because it's not mentioned in the question which one we have to use. we get 14.77....m by using 22/7 and 14.758m by using 3.14. now, considering 14.758m, because it is a RATIONAL number, we get 14.76m when we ROUND it off to two decimal places. therefore the required answer is 14.76m.

Answer»

Step-by-step explanation:

we can answer this by using the FORMULA for circumference of a circle, i.e, 2πr or πd

where r = radius and d = diameter.

therefore, circumference will be

πd because d is given as 4.7 m.

we can use EITHER VALUES for π, 22/7 or 3.14, because it's not mentioned in the question which one we have to use.

we get 14.77....m by using 22/7 and 14.758m by using 3.14.

now, considering 14.758m, because it is a RATIONAL number, we get 14.76m when we ROUND it off to two decimal places.

therefore the required answer is 14.76m.
