Kuhusu kifaa hiki cha kupigia hesabu
A circle calculator works out every property of a circle from a single known value. Tell it whether you know the radius, diameter, circumference or area, enter that value, and it returns all four measurements plus the exact area written as a multiple of π.
Everything is derived from the radius r, using area = π r², circumference = 2 π r, and diameter = 2 r. When you supply a different value it first converts back to the radius: r = diameter ÷ 2, r = circumference ÷ (2π), or r = √(area ÷ π). For a radius of 5, the diameter is 10, the circumference is 2 × π × 5 ≈ 31.42, and the area is π × 25 ≈ 78.54, shown exactly as 25π.
Circle math is needed for pipes and tanks, wheels and gears, circular gardens, pizza and anything round. Because every property follows from the radius, knowing any one of them determines all the others.
Maswali yaliyoulizwa mara nyingi
Ni nini kanuni ya mzingo wa duara?
Circumference = 2 × π × radius, or equivalently π × diameter. A radius of 5 gives a circumference of about 31.42.
Unaweza kupataje eneo hilo?
Rearrange area = π r² to r = √(area ÷ π). This tool does that automatically when you choose to enter the area.
Ni nini eneo la duara lenye ukubwa wa duara 5?
Area = π × 5² = π × 25 ≈ 78.54, shown exactly as 25π.
Je, naweza kuanza kwa kipenyo au mzingo?
Chagua ni kitu gani unachojua kina kipenyo, mzingo au eneo la quamp na kifaa hicho cha kurekodia vitu vingine vitatu.
What is the exact area shown as ×π?
It is the area written as r²π (for example 25π) so the value stays exact rather than being rounded to a decimal.
Kuna uhusiano gani kati ya kipenyo na kipenyo?
Kipenyo ni mara mbili ya ukubwa wa duara, na nusu ya kipenyo ni kipenyo cha 5 na kipenyo cha 10.
API bustanini hutumia kifaa hiki cha hesabu kutoka kwenye mfumo wa sheria
Ipigie simu kifaa hiki cha kupigia hesabu kama Junse É not doot toder. Chochote unachoacha kinatumia kiwango kilekile cha mwisho ambacho ukurasa huu haujakamilika; parameta isiyojulikana ni 400, si sufuri kimya kamwe. Soma habari kamili za API docs →
