0 The circumference of a circle is 9.22cm
Find the length of the diameter.
Give your answer rounded to 2 DP.
de
cm​

Step-by-step explanation:

circumference of a circle = 2πr

9.22 cm = 2*3.14*r

9.22 cm = 6.28*r

9.22 cm /6.28 = r

1.4681 = r

diameter of a circle = 2*r

=2*1.4681

=2.9362

=2.9 cm

The Length of diameter of circle is 2.93cm.

Step-by-step explanation:

Using formula

Circumference of circle = π × d

substitute the values

9.22 cm = π × d

Using value of π = 3.14

9.22 cm = 3.14 × d

divide each side by 3.14

9.22 cm / 3.14 = 3.14 × d /3.14

2.93 cm = d

Hence, The Length of diameter of circle is 2.93cm.

step-by-step explanation:

45.36 feet per second

step-by-step explanation:

tyrone travels 30 miles in 58.2 minutes.  

1 mile = 5280 feet; this means he travels

30(5280) = 158400 feet in 58.2 minutes.

1 minute = 60 seconds; this means he travels 158400 feet in

58.2(60) = 3492 seconds.

this gives us the unit rate of

158400/3492 = 45.36 feet per second.
