Please help me with all these questions . I really appreciate it but if you don't how to do it please comment don't answer the question. Thank you
For number 1, add the sides of the triangle. They are all given. The answer is 19. For number 2, you use the formula for circumference, 2 times pi times radius. The answer is 43.96. For number 3, I assume that 5 is half of one side. You would double 5 to get ten and multiply it by four, since there are four sides in a square. The answer is 40. For number 4, you would multiply 5 times pi, but don't solve it. ( since the directions are to leave the answer in terms of pi) The answer is 5 pi. For number 5, add all the sides together like number 1. The answer is 18.
#2. 43.96 #4. 15.7 I'm not sure about the rest of them but I am good with circles. For #2. do 3.14 times 14 because the radius is 7 and the diameter is 14. Then for number 4 you do the same thing but multiply by 5.
