In a circle, the length of an arc is 6 / 15 of the circumference of the circle. Find the degree of the center angle of the circle opposite the arc Triangle ABC is an equilateral triangle with a side length of 50cm. Draw an arc with points a, B and C as the center and 50cm as the radius, and find the sum of the three arc lengths (Note:
1. 360 * 6 / 15 = 144 degrees
2. 3.14 * (50 * 2) * 60 / 360 * 3 = 314 * 1 / 2 = 157 cm
Given that the radius of the circle is r, the center angle of the arc with arc length of 3 / 4R is___ Radian=_____ Degree (keep π) please, thank you
Radian = (3 / 4R) / r = 3 / 4 angle = radian × （360/（2π））=135/π
1. Multiple choice question: if R is the radius of the circle, the center angle of the arc with arc length of 3 / 4R is () a.135 ° b.135 ° / π c.145 ° d.145 °/
3/4r/2πr *360°=135°/π
Answer: b.135 ° / π
Given that the radius of the circle is R and the arc length is three quarters of R, what is the center angle of the circle opposite to the arc of R
Given that the radius of the circle is R and the arc length is C = 3 * pi * r / 4, how many degrees is the center angle a of the circle?
A=C/R
=(3*PI*R/4)/R
=3 * pi / 4 radians
=(3 * pi / 4) * 180 / PI degrees
=135 degrees
Radian formula Given the radian a of a sector and the horizontal coordinate X of the sector, how to find the vertical coordinate y?
The radius of the sector is equal,
If there is (x, 0), there is (0, x)
A chord of a circle divides the circumference into two arcs with a degree ratio of 1:2. If the radius of the circle is 4, find the length of the two arcs and the circumferential angle of the inferior arc
A chord of a circle divides the circumference into two arcs with a degree ratio of 1:2, then the center angle ratio of the two arc lengths is 1:2, and the circumference angle ratio of the two arc lengths is also 1:2. Center angle of the superior arc: 360 * (1 / 3) = 120 degrees circle angle: 60 degrees inferior arc center angle: 360 * (2 / 3) = 240 degrees circle angle: 120 degrees two arc lengths: superior arc length: (
