Tripling the radius of a sphere increases the surface area by a factor of?
9
If the radius of a sphere is tripled how is the surface area affected?
The surface area of a sphere is directly proportional to the square of its radius. A ∝ r2 r = 3k A ∝ (3k)2 A ∝ 9k2 therefore, the surface area will become 9 times the size
What is the surface area if a sphere with radius of 3?
It is: 4*pi*9 = 36*pi or about 113 square units
What is the surface area of a sphere with a diameter of 6 feet?
1356.48 sq mt Another answer in square feet is : The formula for the surface area of a sphere is 4 x pi x radius squared. The radius is half the diameter, or 3 feet. The radius squared is therefore 9 square feet. The surface area is then 4x3.1415x9 square feet or 113.09 square feet.
What is the surface area of a sphere with a radius of 4.5?
The diameter is 2r = 9 The surface area is Pi x diameter2 = Pi x 81 or 254.469 square units.

If the radius of a sphere is tripled what is going to happen to surface area?
If the radius of a sphere is tripled, the surface area increases by (3)2 = 9 times, and the volume increases by (3)3 = 27 times.
What is the surface area of a sphere with the radius 9?
You can find the surface area of a sphere by solving this equation: SA=4(pi)(r)(r) where SA is your surface area, and r is the radius. Your answer comes out to be about 1017.4 square units.
What is the surface area of a sphere with diameter 18 CM?
Oh, dude, you just need to find the radius first, which is half of the diameter, so that's 9 cm. Then you use the formula for the surface area of a sphere, which is 4πr^2. Plug in 9 for r, square it, multiply by 4, and then multiply by π. That gives you a surface area of 1017π square cm, or about 3190 square cm. Easy peasy!
What is the surface area of a sphere whose diameter is 18 cm?
Oh, dude, you're hitting me with some math here. So, the formula for the surface area of a sphere is 4πr², where r is the radius. Since the diameter is 18 cm, the radius is half of that, which is 9 cm. Plug that into the formula, and you get a surface area of 1017π cm². But like, who's really gonna measure that in real life, am I right?

What is the surface area of a sphere with radius 3?
Formula: 4πr2 Surface Area = 113.09734 units2
What is surface area of a droplet with radius of .00002?
Surface area of a sphere. Area = 4 pi r^2 Area = 4 * pi *(0.00002)^2 = 5.0265 X 10^-9 ( whatever units ) ----------------------------------------------
Tripling the radius of a sphere increase the surface area by a factor?
By a factor of 32 = 9. In general, surface area (for any two similar objects) is proportional to the square of any linear measurement.
