The total surface area of a sphere when the radius is 4 equals 201.1 units2

If the total area of a cylinder is 90pi (282.6) and the height is 12, the radius will be three (3).

For a pipe of uniform radius and thickness, I believe the total surface area would be the Outside surface + Inside surface+ 2 times the surface of the ends. The inside radius(rinner), pipe thickness (t), and pipe length (L) are given.So you only need to find the outside radius (Rout) and then all areas can be calculated.The outside radius should be Rout=rinner +t. And note the perimeter of a circle is 2*pi*Radius and area of an annular region (in this case the ends of the pipe) is A= pi*(Rout2 - rinner2)For the outer pipe surface: Aout=2*pi*(Rout)*LFor the inner pipe surface: Ainner=2*pi*(rinner)*LFor each pipe end: Aend= pi*(Rout2 - rinner2)So the total surface area of the pipe would be: Aout+ Ainner+2* AendOr: Atotal =2*pi*(Rout)*L+2*pi*(rinner)*L+ 2*pi*(Rout2-rinner2)= pi*[ 2*L*(Rout + rinner)]+(Rout2 - rinner2)= 2*pi*[ L*( rinner +t + rinner)]+(( rinner +t )2 - rinner2)]=2*pi*(t+L)(t+2*rinner)Hopefully that is correct and helps.

Total surface area including the two end pieces = (2*pi*radius2)+(2*pi*radius*height) in square units.

Total surface area is 176 units2

With a radius of 3396km, the planet Mars is about the same size as the inner and outer core of the earth (which is around 3490km radius in total).

In our solar system there are four inner planets and four outer planets, for a total of eight.

No. The combined thickness of the inner and outer core is about 3500 to 3520 kilometers, out of the Earth's total radius of about 6370 kilometers. This means that the combination of inner solid core and liquid outer core has about 16% of the Earth's volume. *The reference to "1% of the Earth's volume" may refer to the Earth's crust, which has about "1% of the Earth's total mass."

The inner core has a radius of 1220 kmA extending from the centre of the Earth approximately 6370 km below Earth's surface to 5150 km below the surface (the change from inner to outer core is marked by a density change known as the Lehmann discontinuity). The inner core has a total volume of 7.4207x109 km3.

The core consists of an inner solid core with a radius of 760 miles, and an outer liquid core with a total diameter of 1400 miles. Applying the 4/3pi(r3) volume formula to these values we get: 1.8 billion cubic miles for the solid core and 11.7 billion cubic miles for the total outer and inner core volume. This compares to a total volume for the earth of 32.5 billion cubic miles.

The inner shadow is called the "umbra", while the outer shadow is the "penumbra".

The Earth's core has a radius of approximately 3470 kmA with a total volume of 1.7502x1011 km3 This is separated into the inner and outer core with dimensions as follows: The inner core has a radius of 1220 kmA extending from the centre of the Earth approximately 6370 km below Earth's surface to 5150 km below the surface (the change from inner to outer core is marked by a density change known as the Lehmann discontinuity). The inner core has a total volume of 7.4207x109 km3. The outer core is approximately 2260 km thick extending from 5150 km below Earth's surface to 2890 km (the core mantle boundary or Gutenberg discontinuity) The outer core has a volume of 1.6760x1011 km3.

Length of outer track = sum of length of 10 pieces = circumference of the outer circleif R is the Radius of outer circle then...Circumference of the outer track = 2pi*RSimilarly the circumference of the inner track (with radius r) = 2pi*rlength of each outer piece is 3.4 inch more than length of inner pieceSo total outer length is 10*3.4 =34 inches more than the inner length.=> Outer Circumference - Inner Circumference = 34 inches=> 2pi*R - 2pi*r = 34=> 2pi(R -r) = 34=> R-r = 34/2pi = 5.41 inches=> R-r = Width of the track = 5.41 inches1 year ago

No, not the total core (outer and inner cores combined), anyway. The Earth's outer core roughly starts at a depth of 2890 km. So considering the Earth's 6371 km radius, the total core would be roughly 6962 km in diameter. Mars is 6792 km in diameter. So Mars is around the same size as the Earth's total core (just a bit smaller), but larger than the Earths inner core.
