Answer:
3.26
Step-by-step explanation:
if there is a five you round it up too 3.26
X = 7
y = 10
x + y = 700
7x + 10y = 6400
10x + 10y = 7000
(-) 7x + 10y = 6400
______________
3x = 600
x = 200
200 + y = 700
y = 500
Answer:
Therefore it is possible to find the circumference and area of a circle if we are given the radius or diameter of the circle.
Step-by-step explanation:
i) to find the area of a circle or circumference the radius , r, is required.
ii) if we are given the diameter, d. then we have to find the radius, r, by dividing the diameter by 2, that is .
iii) area of the circle is given by A =
iv) circumference of the circle is given by C =
Therefore it is possible to find the circumference and area of a circle if we are given the radius or diameter of the circle.
