Question

the maximum area of a triangle inscribed in a semicircle with diameter "30" cm is

Answer 1

Step-by-step explanation:

the max. base of the triangle will be equal to diameter. therefore base = 30 cm

then the height of the triangle will be equal to the radius because the distance from the centre to the circumference is equal to radius.

Therefore height = 15 cm.

area = 1/2 × base × height

area = 1/2 × 30 × 15

area = 225 cm²

Answer 2

Answer:

diameter is 30

so find height

diameter /2

30/2

=15

area of triangle = 1/2×base× height

= 1/2×30×15

= 225cm square
