The circumference of a circle with radius of 7 km is 44.0 km (to the nearest tenth), and the area of a circle with radius of 7 km is 153.9 km (to the nearest tenth).
C = 2 pi R
A = pi R2
It depends on what the "32in" refers to: circumference, diameter, radius.
The ratio of the circumference of a circle with radius 4 cm to its area is 1:2.

It is NOT a fraction but a SECTOR. of 7 degres. The regions of a circle are: - Circumference ; all the way around. Radius ; distance from the centre to the circumference Diameter ; Twice the radius and a straight line from circumference through the centre to the opposite side . Chord; a line drawen inside a circle, betwwen two points on the circumference, but NOT touching the centre. Arc ; that part of the circumference that form the curved side of a sector. Sector ; An area inside the circle whose bondaries are two radii and an arc. Tangent ; a line outside the circle just touching the circumference in ONE place.
The answer depends on what the number 0.45 refers to: radius, diameter or area?
To the nearest hundredth, the circumference of a circle with a radius of 4 is 25.13
A circle with a radius of 5 units has a circumference of 31.42 units.
Radius of circle: 132/2pi = 21cm to the nearest integer
A circle with a radius of 4 units has a circumference of 25.13 units.

Circumference of circle: 2*pi*3.5 = 22cm rounded to the nearest whole number
Its radius is 4.8 cm, rounded to the nearest tenth.
Circumference = Pi x 8 = 25.1327 (to nearest 4th decimal)
