What happens where a radius meets the tangent?
The radius and the tangent are perpendicular at the point on the circle where they meet.
When the radius of a circle is doubled what happens to the area?
It quadruples.
What happens to the area of a circle if the radius is tripled?
The circle becomes an oval
What happens to the volume of a cone if the radius is double and the height is unchanged?
Since the volume of a cone is proportional to the square of the radius (look at the formula), double the radius would mean four times the volume.
If the radius of a circle is cut in half what happens to the area?
it is cut down by a factor of four since it is proportional to square of radius
What happens to the diamenter of a circle if you triple the radius?
It will be twice the size of the tripled radius
What happens if you triple the radius in a circle?
nothing you will just just get the radius in 3 circles.
What happens to the circumference of a circle if you triple the radius?
Since circumference is proportional to the diameter (the proportionality is the definition of the irrational number pi) and the radius is just twice the diameter, if you triple the radius, you also triple the circumference.
What happens to the area of a circle if you triple a radius?
When you triple the radius of the circle . . . -- The diameter also triples. -- The circumference also triples. -- The area is multiplied by 9 .
If you triple the radius of a circle what happens to the area?
The result is 9 time the original.
What happens to the area of a circle when the radius is triple?
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.
How do triple the radius?
Multiply the radius by the integer 3.
What happens to the area of a circle when you triple the radius?
As the area of a circle is pi*radius2 the increase in area is a factor of 32. So tripling the radius gives an increase in area by a factor of 9.
If the radius of a circle is tripled what happens to the circumference?
Circumference = pi x diameter so if the radius is 5 then the diameter is 10 Circumference = pi x 10 = 31.415 If we triple the radius to 15, then the diameter is 30, so Circumference = pi x 30 = 94.245 Which looks like triple the first circumference. So if the radius is tripled, the circumference is also tripled.
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.
What happen to the area of circle when the radius is tripled?
If you triple the radius of a circle, the area will increase by 9. Area is proportional to the square of the radius.
Why the area is multiplied by 9 if you triple a radius?
Because the area of a circle is pi*radius2. So, if you triple the radius to 3*radius, the area becomes pi*(3*radius)2 = pi*(32*radius2) = pi*9*radius2 that is, 9 times the original area.
