The circumference of a circle is equal to d(pi) where d is the diameter of the circle and pi is, well, pi.
In case you do not know what pi is, it is an irrational number roughly equal to 3.14159265358979... that is all I remember. If you are still confused, check "circumference" on wikipedia, the free encyclopedia.
Assuming the question refers to a circle with a diameter of 0.9 metres, the circumference is 2.83 m = 2.8 metres to the nearest tenth.
A circle has a circumference of 110.6 mm. Find its diameter to the nearest tenth.
Circumference of the circle: 48*pi = 150.8 inches rounded to the nearest tenth
The circumference of a circle that has a diameter of 34 inches rounded to the nearest tenth is 106.8 inches.
Circumference of a circle = 2*pi*radius or pi*diameter Circumference = 21.67698931 or 21.7 meters to the nearest tenth
diameter = circumference/pi.
10 is a number, not a circle or ellipse. It, therefore, has no circumference.
Its radius is 4.8 cm, rounded to the nearest tenth.
5.1 inches. I rounded to the nearest tenth.
18 x pi = 56.548
The idea is to divide the circumference by (2 x pi).
30.5 is already rounded to the nearest tenths.
4363m to the nearest tenth of a meter is 4363.0m
Circumference = 2*pi*r = 31.4 (to the nearest tenth)
If that's a circle and if 16 cm is the diameter, the circumference is 50.3 and the area is 201.1
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 RA = pi R2
circumference = 2 * pi * radius circumference = 2 * 3.14 * 11.8 circumference = 74.104 Circumference = 2*pi*radius Circumference = 2*3.14*11.8 = 74.104 = 74.1 to the nearest tenth
68 pi mm ie 213.6 mm to the nearest tenth
If its circumference is 8 cm then its diameter = 8/pi = 2.5 cm to the nearest 1/10
If you are talking about 31.30 meters, then rounding to the nearest tenth of a meter would give you 31.3 meters.
Circumference of a CircleThe distance around a circle. It is equal to Pi () times the diameter of the circle. Pi or is a number that is approximately 3.14159. Example:What is the circumference of a circle having a diameter of 7.9 cm, to the nearest tenth of a cm? Using an approximation of 3.14159 for , and the fact that the circumference of a circle is times the diameter of the circle, the circumference of the circle is Pi × 7.9 3.14159 × 7.9 = 24.81…cm, which equals 24.8 cm when rounded to the nearest tenth of a cm.or you could just measure it using a string and save yourself the math
