A circle has a circumference of 110.6 mm. Find its diameter to the nearest tenth.
Circumference circle = pi* r^2 Load and crunch previous formula was for area. The correct answer is 2*Pi*r = 24*Pi = 75.4 cm (rounded to nearest tenth). I stand corrected. One needs be more careful. Thank you.
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.
The area of the circle would be 483.1 units squared.
The area of a circle to the nearest tenth if its radius is 4.5 is: 63.6 square units.
Its radius is 4.8 cm, rounded to the nearest tenth.
If I remember correctly Area of a circle is... PIE multiplied by the RADIUS squared. If this is so.... 15 is the radius and... The sum of 15 x 15 should be multiplied by pie (3.1415 or what ever it is). Use a calculator to get to the nearest tenth.

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
Using 3.14 as Pi the area of circle is: 12.56
If the circle's radius is 2.5 kilometers, then its diameter is exactly 5.0 kilometers, with no rounding required.
Circumference of a circle = 2*pi*radius or pi*diameter Circumference = 21.67698931 or 21.7 meters to the nearest tenth

2*radius*pi or diameter*pi, pi = 3.14 (rounded to the nearest tenth)
r = sqrt(400/pi) = 11.3 cm
