Mathematics
1 answer:
Finger [1]4 years ago
6 0

Answer:

The radius of circle is 10.5 units

D is correct

Step-by-step explanation:

We are given a circle with centre M

We need to find the radius of circle.

Radius: It is distance from centre to a point on circle.

In figure,

Center at M

Points on circle, R and S

Radius should be RM, SM

From figure,

RM=10.5 units

SM=10.5 units

RM=SM=10.5 units

Hence, The radius of circle is 10.5 units

Pythagorean theorem in 3D.
White raven [17]

Answer:

<em>h = 6.2</em>

Step-by-step explanation:

You need to find h.

The dashed triangle is a right triangle. 8 is the hypotenuse. h is a leg. The other leg is the half of the side of the base, 5.

5^2 + h^2 = 8^2

h^2 + 25 = 64

h^2 = 64 - 25

h^2 = 39

h = \sqrt{39}

h = 6.244998...

h = 6.2

Solve -5 + w/3 = -1.
Liula [17]

Answer:

w = 12

Step-by-step explanation:

-5 + w/3 = -1

w/3 = 4 (Add 5 to both sides)

w = 12 (Multiply 3 by both sides)

A human brain weighs about 1 kg and contains about 1011 cells. Assuming that each cell is completely filled with water (density
elena-s [515]

Answer:

Step-by-step explanation:

From the information given:

a human brain weighs = 1 kg ; = 1000 grams

Number of cells = 10¹¹ cells

The density of water filled in each cell = 1 g/mL

From above;

the weight of each of the brain cell = total weight of the human brain/the number of cells

the weight of each of the brain cell = 1000/10¹¹

the weight of each of the brain cell = 1 × 10⁻⁸ grams

Now, to calculate the quantity of water in each cell; we have:

= the weight of each brain × density

= 1 \times 10^{-8} \ g \times \dfrac{1 \ mL}{1   \ g}= 1 \times 10^{-8} \ mL

For cube; we know that

1 mL = 1 cm³

Thus:

1 \times 10^{-8} \ mL=  1 \times 10^{-8} \ cm^3

Recall that; the volume of a cube as well = x^3

where;

x = length of each sides

∴

x^3 = 1 \times 10^{-8} \ cm^3

x = \sqrt[3]{1 \times 10^{-8}}

x = 0.0022 cm

Thus, the length of each side of the cell = 0.0022 cm

The surface area of a single cell = x²

The surface area of a single cell = (0.0022 cm)²

The surface area of a single cell = 4.84 × 10⁻⁶ cm²

Therefore, the total surface area of  is:

1 \times 10^{11}  \ cells \times \dfrac{4.84 * 10^{-6} \ cm^2}{1 \ cell}

= 4.84 \times 10^5 cm^2

= 5.0\times 10^5 cm^2

= 50 m²
