If the radius is tripled then the Area will be greater by a factor of 9.
And the circumference will be greater by a factor of 3.
The original volume is multiplied by 27.
Circles with the same radius are congruent circles.
It's not a circle if it's radius of 5 degrees. If it's 5 cm radius, then 12 circles.
congruent
The ratio of radius to diameter for any circle is 1/2
It will be twice the size of the tripled radius
The circle becomes an oval
The original volume is multiplied by 27.
nothing you will just just get the radius in 3 circles.
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.
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.
It is increased nine fold. New Area = 9*old area.
Circles with the same radius are congruent circles.
Circumference(C) = 2πr C is directly proportional to r. If radius is tripled then circumference becomes three times of the initial. Since the radius is tripled so the new radius is 3r. New circumference(C') = 2π(3r) = 3 x (2πr) = 3 x C Area = πr2 A is directly proportional to r2. If radius is tripled then area becomes 9{square of 3} times of the initial. New radius is 3r. New Area(A') = π (3r)2 = 9 x π r2 = 9 x A.
The question is misguided. You do not use radius only on circles!
If you triple the radius of a circle, the area will increase by 9. Area is proportional to the square of the radius.
it looks like a circle.
