Question

An object goes round a circular track of radius 7m. Calculate the distance covered by the object in one and half round of its journey

Answer 1

Answer:

GD

r=7m

then , c =2 pi r

= 44m

so half of it= 22m

so,total = 22 + 44

= 66m

Answer 2

Answer:

Area of circle=πr2

Step-by-step explanation:

then in one round πx7x7=49π

and in half round πx7x7/2=49π/2

after we add these two steps

49π+49π/2=147π/2
