Answer:
Step-by-step explanation:
The shaded region is the difference of areas of semicircle AB and triangle ABC.
ABC is right triangle as AB is diameter, so C is right angle.
<u>Area of semicircle:</u>
- A = 1/2πr² = 1/2*3.14*4² = 25.12 cm²
<u>Area of triangle:</u>
- A = 1/2BC*AC = 1/2*4*
= 2
= 13.86 cm²
<u>Shaded are is:</u>
- 25.12 - 13.86 = 11.26 cm²
Hi! For the area of a parallelogram, we just need to multiply the base and the height. It may sound simple but the tricky part in this problem is determining which one is the height.
For a parallelogram, the height is defined as the measurement PERPENDICULAR to the base. Therefore, for this problem, we need to multiply 14 and 4.5 instead of 14 and 6.
ANSWER: B. 63 square meters.
Answer:
/
Step-by-step explanation:
firstly we make two steps to simplify this question.
1st step: simplify 
to simplify this we use factorization


.....(1)
2nd step:simplify 


.....(2)
now dividing (1) and (2), we get the answer

Answer:
E. People once thought animals were individually create by some superior.
But the solid creation of theory of origin of species by the naturalist Charles Darwin demonstrated a different theory.
Step-by-step explanation:
Before Charles Darwin several scientists were discussing the hypothesis of a theory of evolution. But it was Darwin whom put together all the information with reliable explanation and correlation between animal specialization and environment accordyinly with time.
He spent almost five years on board the ship HMS Beagle, crossing several continents, starting with South America. From there, he returned with dozens of specimens of living species, illustrations and fossils. Those specimens helped Darwin in his discoveries which originated the book On the Origin of Species published in 1859.
