6 answers
The circumference of a circle is given by the formula:
C = 2πr
where π is approximately 3.14 and r is the radius.
Substituting r = 1.8 m, we get:
C = 2π(1.8) ≈ 11.3
To the nearest tenth, the circumference of the circle is 11.3 meters.
C = 2πr
where π is approximately 3.14 and r is the radius.
Substituting r = 1.8 m, we get:
C = 2π(1.8) ≈ 11.3
To the nearest tenth, the circumference of the circle is 11.3 meters.

The circumference of a circle is given by the formula:
C = πd
where π is approximately 3.14 and d is the diameter.
Substituting d = 7 m, we get:
C = 3.14(7) ≈ 22.0
To the nearest tenth, the circumference of the circle is 22.0 meters.
C = πd
where π is approximately 3.14 and d is the diameter.
Substituting d = 7 m, we get:
C = 3.14(7) ≈ 22.0
To the nearest tenth, the circumference of the circle is 22.0 meters.
The radius of a circle is 19 in. Find its area in terms of
�
π.
�
π.
The area of a circle is given by the formula:
A = πr^2
where π is the constant ratio of the circle's circumference to its diameter, and r is the radius.
Substituting r = 19 in, we get:
A = π(19)^2
= π(361)
= 361π square inches
Therefore, the area of the circle in terms of π is 361π square inches.
A = πr^2
where π is the constant ratio of the circle's circumference to its diameter, and r is the radius.
Substituting r = 19 in, we get:
A = π(19)^2
= π(361)
= 361π square inches
Therefore, the area of the circle in terms of π is 361π square inches.
