The diameter is 9.3 meters what is the circumference and area?
To find the circumference of a circle, you can use the formula C = πd, where C represents the circumference, π is a constant value approximately equal to 3.14, and d is the diameter of the circle.
In this case, the diameter is given as 9.3 meters. So, to find the circumference, we can substitute this value into the formula:
C = πd
C = 3.14 × 9.3
C ≈ 29.202 meters
Therefore, the circumference of the circle is approximately 29.202 meters.
To find the area of a circle, you can use the formula A = πr^2, where A represents the area and r is the radius of the circle. Since we have the diameter, we can find the radius by dividing the diameter by 2:
r = d/2 = 9.3/2 = 4.65 meters
Now, we can substitute the radius into the formula to find the area:
A = πr^2
A = 3.14 × (4.65)^2
A ≈ 67.195 square meters
Therefore, the area of the circle is approximately 67.195 square meters.
C = pi * d
A = pi * r^2
