the radius is from the center of the circle to the edge so that's how you find the radius.
If the radius of a circle is tripled, how is the length of the arc intercepted by a fixed central angle changed?
The volume is Base x height; the Base area is the same as the formula for a circle - which is proportional to the square of the radius. For example, if you double the radius (or the diameter, or the circumference) of a circle, its area will quadruple.
The segment you describe is the radius of the circle.
no.the radius of a circle is the distance from the middle of the circle to the edges. no.the radius of a circle is the distance from the middle of the circle to the edges.
The radius of the circle is: 9.549 cm
The area of the circle will be 4 times greater
It quadruples.
The area quadruples.
the area of the circle is increased by 400%
If the radius of a circle is tripled, how is the length of the arc intercepted by a fixed central angle changed?
A circle does not have volume since it is a 2 dimensional shape. Volume requires 3 dimensions.
The circumfrence would double Example : C of 5 cm radius circle = 3.14 *2*5 C=3.14 C of 10cm radius circle = 3.14*2*10 C =62.8
300. (Doubling the radius multiplies the area by four times.)
The area increases as the square of the radius (or diameter). So if you double the radius you * 4 (quadruple) the area. Treble the radius, you *9 the area.
Circumference = 2 x π x radius double radius: new_circumference = 2 x π x (radius x 2) = (2 x π x radius) x 2 = circumference x 2 → if the radius is doubled, the circumference is doubled.
The volume is Base x height; the Base area is the same as the formula for a circle - which is proportional to the square of the radius. For example, if you double the radius (or the diameter, or the circumference) of a circle, its area will quadruple.
