What is the area of a circle of radius (a) 5.142 m and (b) 1.7 m?

(a) Area = (b)  Area =

Explanation:

We have given radius of the circle r = 5.142 m and r = 1.7 m

We have to find the area of the circle

We know that area of the circle is given  by

, here r is the radius of the circle

(a) Radius = 5.142 m

So area

(b) Radius = 1.7 m

So area

this could be newton#'s law of cooling. the cooling curve is exponential

the answer to this is proletariats.

hope this : )
