What is the formula for finding the circumference with radius?
the circumference is two times the radius, or 2r. so if the radius was 3, the circumference would be 6. if the radius was 4, the circumference is 8.
How do you get the radius of a circle from the circumfrance?
To find the radius of a circle when given the circumference, you should start with the formula for circumference, which is this: circumference = 2*pi*radius To solve for the radius, you would the have to divide the circumference by 2*pi leaving you with a formula like this: radius = circumference/(2*pi) pi≈3.14159
What would the answer be if the radius is 5 and the diameter is 10 what would the circumference be?
Circumference = 2*pi*radius or pi*diiameter Circumference = 31.416 units rounded to 3 decimal places
When the radius of a circle is tripled what happens to the perimeter and area of the circle?
The perimeter would triple and the area would be multiplied by nine (32). Circumference (perimeter) is (2 x pi x r), so would be (6 x pi x r) for triple the radius, and area is (pi x r2), so would be (pi x 32 x r2) for triple the radius.
How do you get the radius of the circle with the circumference?
divide the circumference by pie (3.14) and the answer would be the radius. for example circumference = 314 pie = 3.14 so 314 divide by 3.14 = 100 so the radius = 100
What do you think would happen if you halved the radius of a circumference?
circumference would be halved, area would be one fourth of original , andvolume would be one eighth of original.
What is the formula for finding the circumference with radius?
the circumference is two times the radius, or 2r. so if the radius was 3, the circumference would be 6. if the radius was 4, the circumference is 8.
Why would the perimeter triple and the area multiply by nine when the radius of a circle is tripled?
Because the perimeter (circumference) is 2*pi*r is proportional to r. The area a = pi * r2 is proportional to r2
Radius is 8 what is the circumference?
16. The radius is half of the circumference. So you would multiply the radius by two. * * * * * Wrong! Circumference is 2*pi*radius = 50.27, approx.

If the circumference of a circle is tripled what happens to its radius?
The radius is tripled, too. Suppose: (1) C = 2πr (2) C' = 2πr' (3) C' = 3C Then C' = 3(2πr) = 2π(3r) But C' = 2πr', so 2πr' = 2π(3r) and finally r' = 3r.
If radius of a circle is 9 centimeters what would be the circumference?
If radius of a circle is 9 centimeters the circumference would be: 56.55 cm (r x 2 x Pi = circumference).
What would the answer be if the radius is 5 and the diameter is 10 what would the circumference be?
Circumference = 2*pi*radius or pi*diiameter Circumference = 31.416 units rounded to 3 decimal places
How do you get circumference when you are given radius?
Circumference is equal to pi x diameter Diameter is equal to 2 times the radius Circumference would be 2 x pi x radius
What is the radius of a circumference of 64cm?
The radius of a circumference is half of the diameter. To find the radius of a circumference with a length of 64cm, you need to divide the circumference by 2Ο (since the formula for the circumference of a circle is C = 2Οr). So, the radius would be 64cm / (2Ο) β 10.19 cm.
When the radius of a circle is tripled what happens to the perimeter and area of the circle?
The perimeter would triple and the area would be multiplied by nine (32). Circumference (perimeter) is (2 x pi x r), so would be (6 x pi x r) for triple the radius, and area is (pi x r2), so would be (pi x 32 x r2) for triple the radius.
