The area is proportional to the square of the diameter. So, if the diameter changes by a factor 0.75, the area changes by a factor of 0.752.
When the diameter of a sphere is decreased by 25%, its curved surface area decreases by approximately 43.75%. This is because surface area is proportional to the square of the radius, so a 25% decrease in diameter leads to a 43.75% decrease in surface area.
Yes, as a convex lens becomes more curved, its focal length decreases. This is because a more curved lens causes light rays to converge at a point closer to the lens, resulting in a shorter focal length.
As the sides of a convex lens become less curved, the focal length increases. This change is due to the decreased curvature causing light rays to converge at a point farther away from the lens. The lens will have a weaker converging effect, resulting in a longer focal length.
A curved path followed by a projectile is called a trajectory. This is the path that an object takes when it is thrown or launched into the air.
The reflecting surface of a mirror is flat.
Curved motion is typically caused by the presence of a force that is not aligned with the direction of motion. This force can be due to factors such as gravity, electromagnetic forces, or friction. The object experiencing the curved motion will deviate from a straight path and follow a curved trajectory as a result of the applied force.
The surface area decreases by 43.75%.
Surface area, S.A., of a sphere with radius r equals to 4pir2.Since the diameter is decreased by 25%, the radius is also decreased by 25%.That is r - 0.25r = 0.75r.So that S.A. = 4pi(0.75r)2 = 2.25pir2
The curved surface are is: pi*diameter*height
The curved surface area of a cylinder with a height of 8cm and diameter of 10cm is 251.33cm2
The curved surface area of a cylinder that has a diameter of 8inches and a height of 5inches is 125.66inches2
The curved surface area of a cylinder with a diameter of 1 and a height of 2 is 6.28 units2
The curved surface area of a cylinder having a height of 5.25 and diameter of 1.75 is 28.588 units squared.
A diameter is a straight line from one side of a circle, through the centre, to the other side. A circumference is the curved line forming the boundary of a circle.
The curved surface area is 75.4cm2
The curved surface area is 904.78cm2
If it's a circle, then the formula is ╥d (Pi (3.14) times the diameter)
The curved surface area is 502.65m2
