What is the effect on the volume of a sphere when the diameter is doubled?
The volume is increased by 8 times when the diameter of the sphere is doubled.
What will be the percentage increase decrease in the volume of a sphere if its radius is doubled?
Originally Answered: If the radius of a sphere is doubled by what percent will its volume increase? In percentage terms this is a 700\% increase.
Does doubling the volume of a sphere have the same effect on the radius?
To double the volume, we have to increase the radius by multiplying it by 3√2 .
What is the percentage increase in the volume of sphere when its surface area is increased by 21?
33.1 \%
Hence, the percentage increase in volume is 33.1 \%
What is the percentage change in the surface area of a sphere if its radius is doubled?
THE DOUBLED RADIUS OF THE SPHERE = 2r. DOUBLED RADIUS SURFACE AREA = 4π(2r)² = 16πr² . INCREASE \% IN AREA = 16πr²-4πr²/4πr² × 100 = 12/4 × 100 = 300\% . HOPE THE ANSWER IS CORRECT.
When the radius of sphere is double by how much percentage will its area changed?
Hence, the surface area of the sphere will increase 4 times if the radius of that sphere is doubled.
What percentage increase in the radius of a sphere will cause its volume to increase by 45?
45\% increased volume = 145\%V.
What is the formula to find the volume of a sphere?
Sphere Formulas Diameter of a Sphere D = 2 r Surface Area of a Sphere A = 4 π r 2 Volume of a Sphere V = (4 ⁄ 3) π r 3
What is the radius of the new sphere if radius is doubled?
If the radius of a sphere is doubled, it volume becomes ….. times the original volume. If the radius of a sphere is doubled, it volume becomes ….. times the original volume. Let r be the radius of the original sphere. ×π×r 3. Now if the radius be doubled then the radius of the new sphere will be 2r. ×π×(2r) 3=8V.
What is the increase in diameter of B over a?
The increase in diameter or radius of B over A = (6.32–5)*100/5 = 26.49110641 \% for an increase of 60\%in the surface area of B over A. Answer. If the curved surface area of a sphere increased by 44\%, then by what percentage would its volume increase?
What is the percentage change in diametre when surface area is 44\%?
Originally Answered: If the surface area of a sphere is increased by 44\%,what is the percentage change in the diametre? The surface area is increased by 44\%, that means the area is now 144\% or 1.44 times the original surface area.
