Find the sum of 2.5+3.03
Alenkasestr [34]

Answer: 5.53


Step-by-step explanation:

this is a straight forward addition

2.5+3.03 =5.53

to be clear or to specify, use the decimal point to make the sum:

2.5 = 2 + 0.5       and 3.03 = 3 + 0.03

2+3= 5      and  0.5 + 0.03 = 0.53

5 + 0.53 = 5.53 (but this is to long just to make it clear)

Is anyone good with this? I need help finding the answer.

To solve this problem, we have to find the perimeter of the shape.
we already know that two of the sides are 82m, all we need to do is find the circumference of the semicircles.
to find circumference, you multiply the diameter of a circle by pi. since we have two identical semicircles, we have one full circle. 66•3.14=207.24
207.24+82+82=371.24
the answer is 371.24m
