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 .
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.
What happens to the cylinder's surface area if its radius is squared?
It remains the same or increases in surface area.
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 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.
What happens to the surface area of a sphere if its radius is doubled?
If the radius of a sphere is doubled, the surface area increases by (2)2 = 4 times, and the volume increases by (2)3 = 8 times.
What happens to the surface area of a cube if all sides triple?
It increases nine-fold.
What happens to the Surface Area and Volume of a pyramid if the radius and height are divided by 2?
The surface area is reduced by a factor 4, the volume by a factor 8.
What is the surface area of sphere with radius 13ft?
The surface area of a sphere with a radius of 13ft is about 2,123.7ft2
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.
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 is the surface area of a sphere with a radius of 5 m?
The surface area of a sphere with a radius of 5m is 314.2m2
