Answer:
c.132
Step-by-step explanation:
so we are given the diameter which is 42m **the diameter is the straight line that passes through the middle of the circle**
but in order to find the circumference we need to find the radius **the radius is always half (1/2,0.5) of the diameter**
so we have to divide 42/2 which equals 21
now we need to set up the formula;
c=2πr/c=2xπxr **when unknown variables such as 'r' are next to another mathematical numeral such as the pi symbol you don't really have to but the multiplication symbol between them**
c=2π21
=131.946891451
and in your case, it seems we must round to the tenths place so the nine then "becomes a ten" and you're left with 132
good luck :)
i hope this helps
have a good one !!

Take square root to get:
To the nearest tenth we have
Answer:
12
Step-by-step explanation:
As we can see in the picture, the bigger pentagon is a scale copy of the smaller one with a scale factor of 2. Hence, all the sides on the smaller pentagon multiplied by 2 gives us the bigger pentagon. We can find the scale factor by looking at the biggest side of the pentagon. Hope this helped, Thank you.
