Question

The difference between areas of traingle of largest area inscribed in a circle of radius r units and a triangle of largest area inscribed in a semicircle of radius r unit is

Answer 1

Answer:

hy ur answer is

Step-by-step explanation:

The area of a triangle is equal to the base times the height.

In a semi circle, the diameter is the base of the semi-circle.

This is equal to 2×r (r = the radius)

If the triangle is an isosceles triangle with an angle of 45

∘

at each end, then the height of the triangle is also a radius of the circle.

A = 1/2 ×b×h formula for the area of a triangle becomes

A = 1/2 ×2×r×r because:

The base of the triangle is equal to 2×r

The height of the triangle is equal to r

A = 1/2 ×2×r×r becomes:

A = r^2
