Question

can anyone tell me area of triangle , circumference of circle , semi circle, larger circle​

Answer 1

Answer:

Here is your answer hope it helps....

Step-by-step explanation:

area of triangle= 1/2× base × height

circumference of circle = 2πr

circumference of semi circle= πr+d

NOTE CIRCUMFERENCE OF CIRCLE AND LARGE CIRCLE IS SAME

Answer 2

Answer:

triangle- A = hbb/2 , circle - C= 2πr , semi- half of the circumference of the circle and diameter. As the perimeter of a circle is 2πr or πd. So, the perimeter of a semicircle is 1/2 (πd) + d or πr + 2r, where r is the radius., large- sorry I don't know
