Denise is the fastest runner. 40 divided by 6 is 6.666 repeating 30 divided by 5 is 6 and 20 divided by 4 is 5 therefore denise is fastest
Answer:
Dimensions = 8 CM and 12 CM
length = 12 CM
width = 8 cm
perimeter = 2 ( length + width)
= 2( 12 + 8)
= 2 ( 20)
= 40 CM
ratio = 12/40
= 6/20
= 3/10
<h2>= 3 : 10 </h2>
Move the decimal point one to the right on both sides so it would be 70/203. After that you can divide it by adding more 0s to 70. Like, 70.00 until you get an answer
The formula is
SA= pi (r)2 +pi (r) (h)
the SA is 13,188
