30 inches diameter or
93 inches circumference
An experiment is an example of an exercise.
Divide the circumference by pi, divide the result by 4, and finally, multiply the result by the original circumference. Ex. The circumference of a circle is 43.96 units long. What is the area of the circle? (use 3.14 as pi). Solution: First, divide 43.96 by pi, which is 3.14 in this question. The result should be 14. Next, divide 14 by 4,getting 3.5. Finally, multiply 3.5 by the original circumference, which was 43.96, and the final result should be 153.86. The answer to the example is 153.86 square units.
Assuming it is to be kept in proportion, 13.5 inches
A tape measure would be the tool, measuring in centimetres or inches.
about 22-30 inches I should say.
Circumference = pi * diameter C = pi(3.14159 should do) * 30 inches = 94.2478 inches circumference
A circle with a radius of 8 inches has a circumference of 50.27 inches.
If the circumference is 1.59 inches , then the radius should be (1.59/2pi) inches. So , the area will be - (pi)*(1.59/2pi)2 = (1.59)2/4pi
The circumference of the earth is about 24,880 miles, so a globe with a circumference of 43 inches would have a scale of approximately 578 miles per inch.
10 inches * * * * * Actually it is 10.504 which should be rounded to 11 inches.
It should be anywhere from 6 and half inches to 13 inches with a circumference of 8 inches.
Thee formula for the circumference of a circle should read 2*pi*radius or pi*diameter. In which case using either formula its circumference is 88 inches rounded.
never mind i got the answer... The Answer Should Be 4
A Basketball goal, or hoop, is about 56½ inches in circumference (56.55 inches). The rim is 18 inches in central diameter, and the top of the rim should be exactly 10 feet off the ground.
The circumference of a circle is worked out by Pi x Diameter. To do this accurately the Pi button on a scientific calculator should be used. If you don't have one of these take Pi to be 3.14.The answer would be Pix8.5This works out to be 26.70353756 inches and should probably be rounded to 3 significant figures making it 26.7 inches.
Circumference = 2 x π x radius ⇒ radius = circumference ÷ (2 x π) So divide the circumference by 2 x π ~= 2 x 3.14 = 6.28 ⇒ radius = 22 inches ÷ 6.28 ~= 3.5 inches. As an approximation to π (the ratio between a circle's circumference and its diameter), the value 22/7 is sometimes used (to 2 decimal places 22/7 = 3.14 & π = 3.14). The circumference given as 22 inches suggests this approximation should be used: 22 ÷ (2 x 22/7) = 22 x 7/22 ÷ 2 = 7 ÷ 2 = 3.5
A basketball hoop is 18" in diameter and the formula for circumference is pi x 18" (3.1415 x 18"=56.54866")
