Step-by-step explanation:
1.what is asked?
find the circumference of bea's circular spa
Given:radius of 2 meters
solution:
formula of cicumference=2πr
C=2(3.14)(2)
C=6.28(2)
C=12.56meters
the circumference of bea's spa is 12.56 meters
2.given:diameter=8meters
C=πd
C=3.14(8)
C=25.12meters
the circumference of circula pool is 25.12 meters
3.C=2πr
C=2(3.14)(32)
C=6.28(32)
C=200.96meters laces will be needed
4.
C=3.14(15)
C=47.1
5.C=2πr
C=2(3.14)(16)
C=6.28(16)
C=100.48in
