Answer:

Splitting the figure into triangles , rectangles and square

First triangle : base = 2 , height = 2

Area = 1/2 x 2 x 2 = 2 square units

Rectangle : length = 5 , breadth = 2

Area = 5 x 2 = 10 square units

Rectangle : length = 7, breadth = 1

Area = 7 x 1 = 7 square units

Rectangle : length = 6, breadth = 1

Area = 6 x 1 = 6 square units

Triangle : base = 3, height = 3

Area = 1/2 x 3 x 3 = 4.5 square units

Square : side = 3

Area = 3 x 3 = 9 square units

Total Area = 2 + 10 + 7 + 6 + 9 + 4.5 = 38.5 square units

Scientific understandings can change as new information is discovered. Which is an example of how scientific understandings have

Tresset [83]

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.

Find the area of the largest square contained by a circle of radius r = 1cm. Explain your answer and justify that it is correct.

Elena-2011 [213]

Answer:

2 square cm

Step-by-step explanation:

Given :

A square is inscribed in a circle whose radius is r = 1 cm

Therefore, the diameter of the circle is 2 r = 2 x 1

= 2 cm.

So the diagonal of the square is 2r.

Using the Pythagoras theorem, we find each of the side of the triangle is $r \sqrt 2$ .

Therefore, the area of the square is given by $\text{(side)}^2$

= $(r\sqrt 2)^2$

$= 2 r^2$

$= 2 (1)^2$

$=2 \ cm^2$

Hence the area of the largest square that is contained by a circle of radius 1 cm is 2 cm square.

Angle G is a circumscribed angle of circle E. Major arc FD measures 280°.

mixer [17]

Answer:

The answer is 40°

Step-by-step explanation:

Solution

Now,

The Measure of major arc FD = 280°

Thus,

One complete angle measure 360°

Then

m∠FED = 360 - 180

m∠FED = 80°

Thus,

FE = DE ( the same circle Radius)

∠EFD = ∠EDF ( opposite angles to equal sides are equal)

Now

Applying angle sum property of a triangle in ΔEFD

∠EFD + ∠EDF + ∠FED = 180°

∠EFD + ∠EFD + 80 = 180

2∠EFD = 100

∠EFD = 50°

Hence, GF is tangent to the circle and the tangent always make right angles with the radius of the circle.

∠EFG = 90°

∠GFD + ∠EFD = 90°

∠GFD + 50 = 90

∠GFD = 40°

Therefore, The measure of the angle GFD is 40°
