The lens of a telescope has a radius of 1 meter what is the lens area use 3.14
The lens area is:
πr^2 = π(1m)^2 = 3.14 square meters
Therefore, the lens area of the telescope is 3.14 square meters.
To calculate the area of a lens, we can use the formula for the area of a circle, which is given by:
Area = π * r^2
where π (pi) is an irrational number approximately equal to 3.14159, and r is the radius of the circle (in this case, the radius of the lens).
Given that the radius of the lens is 1 meter, we can substitute this value into the formula:
Area = 3.14 * (1^2)
Area = 3.14 * 1
Area = 3.14 square meters
Therefore, the area of the lens is approximately 3.14 square meters.
