Question

if the triangle of base 6cm has the same area as circle of radius 6cm the altitude of triangle is​

Answer 1

Area of the circle:—

==>πr²

==>(22/7)×6×6

==>792/7cm²

Now we know that:—

Area of circle=Area of triangle and hence:-

Area of triangle=792/7cm²

Also,

Area of triangle=1/2(base×hight)

Hence,

==>$\frac{792}{7} = \frac{1}{2} \times 6 \times h$

==>$\frac{792}{7} \times \frac{1}{3} = h$

.

Hence the answer and also, the hight of the triangle is 264/7cm

Answer 2

Step-by-step explanation:

Area of Δ=area of circle

= 1 /2 ×base×altitude=πr

=1/2 ×6×altitude=π×6×6

altitude=12πcm
