The surface area of a sphere with a radius of nine is 1,018 units2.
1017.88
The surface area of a sphere is SA = 4 pi (r2)
pi x 324 = 1017.876
Surface area = 4 pi * r**2
so with radius 9, the surface area = 324 * pi ~= 1017.876
972 pi units 3 - apex
324 pi units^2

What is the volume of a sphere when the radius is 3x3?
A sphere with a radius of 9 units has a volume of 3,053.63 units3
What is the surface area of a right cone with a slant height of 6 and a radius of 9?
These dimensions are not possible for a right cone. The radius must be less than the slant height. If we reverse the dimensions (radius 6, slant height 9) the total surface area will be about 282.74 units2
What is the area of the cross section of a sphere that is 3 units from the center of the sphere?
The cross section at this point forms a circle and its area is pi/32 which equals 9*pi square units. * * * * * Not quite. If the radius of the sphere is R units then the radius of the cross section is sqrt(R2 - 32) Therefore the cross sectional area is pi*(R2 - 32) square units.
What is the total surface area of a solid hemisphere of radius 9cm?
The surface area of a sphere is 4 x pi x r x r so in our case (since we have only half a sphere (hemisphere) the surface ares would be (0.5) x 4 x pi x 9 x 9 =162 x pi square cm. But now you have to add the area of the base because it gets exposed when youcuta sphere (to get the hemisphere) and the area of the base would be pi x r x r = pi x 9 x 9 = 81 x pi square cm. So add the two results to get 243 x pi = 763.4 square cm
What is the total area of a cone with the radius of 5 cm and slope height of 9 cm?
A cone with the radius of 5 cm and slope height of 9 cm has a total surface area of approximately 219.91cm2
Surface area of a sphere with a radius of 9?
The sphere's surface area is ~1,017.9 square units.
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
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 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 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.
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.
