Circumference= 2*pi*r=24pi
then pi*r=12pi
the r=12
area =pi*r^2=(12)^2*pi=144 pi cm^2
Answer:
Fossils can be defined as remnants of plants and animals that have lived on the earth many years ago. Coal can be defined as a solid type of fossil fuel which is formed from decayed plants.
Coal arises from different plant debris such was roots, leaves, trees that settle in swamps, the seperation and gathering of these debris forms what is known as "peat". Folds of the peat covered by sediment is exposed to heat and pressure for millions of years to form coal.
Answer:
A). Specialization
Explanation:
Specialization is defined as 'the act of focusing upon a particular skill, product, or field' and this is the factor associated with the agricultural sector that allows each of the sectors to yield maximum efficiency while performing the tasks. This process helps in centralizing the resources(the process of integration of specialized production) like land, capital, labor on the production of a selected variety of goods. Thus, each sector is able to concentrate upon the new techniques or methods to ensure its maximum efficiency without any change and hence, <u>option A</u> is the correct answer.
