You are standing next to a really big circular lake. You want to measure the diameter of the lake, but you don't
want to have to swim across with a measuring tape! You decide to walk around the perimeter of the lake and
measure its circumference, and find that it's 4007 m.

1 275.5 m

Step-by-step explanation:

Measure of the circumference = 4007

on the other hand ,the Measure of the circumference = (diameter)×π

then

the measure of the diameter = 4 007÷π = 1 275.46771393845 m

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer

7

step-by-step explanation:

i'm assuming you need to figure out how many campers go into each tent.

i got the answer by:

24+4=28

28/4=7
