The circumference of a circle is 15.2mm. Find the length of the radius.
Give your answer rounded to 1 DP. HELP PLS

r = 2.4

Step-by-step explanation:

Given, circumference = 15.2 mm

We know that, circumference = 2πr

So, 2πr = 15.2 mm

=> 2(3.14)r = 15.2

=> 3.14r = 15.2/2

=> 3.14r = 7.6

=> r = 7.6/3.14

=> r = 2.42...

=> r = 2.4 [rounded to one decimal place]

your answer is 228

step-by-step explanation:

add the top and bottom bases together, then divide them by 2, then multiply by the height.
