The circumference of the circle
is given by the equation C = pi * D. Incorporating the length of the diameter
into the equation, we have,
C = pi * D
C =
pi * 7cm
C =
21.99 cm
The answer is to that is 100
25times 4
The awnser for question 5 is 4/6
2 times 2.5 times 1.5 times 10 equals to 75 square meters.
