1. Earth is approximately a sphere of radius 6.37х106 m. what are (a) its circumference in kilometers, (b) its surface are in sq

Minchanka [31]

As we know that circumference of the sphere is given as

$C = 4\pi R$

here we know that

$R = 6.37 \times 10^6 m$

now we have

$C = 4\pi (6.37 \times 10^6)$

$C = 8\times 10^7 m$

$C = 8 \times 10^4 km$

PART B)

surface area of the sphere is given as

$A = 4\pi R^2$

$R = 6.37 \times 10^3 km$

$A = 4\pi (6.37\times 10^3)^2$

$A = 5.1 \times 10^8 km^2$

PART C)

Volume of the sphere is given as

$V = \frac{4}{3}\pi R^3$

here we have

$V = \frac{4}{3}\pi(6.37 \times 10^3)^3$

$V = 1.1 \times 10^{12} km^3$

The conversion for km to inches is:

1km=39370.1in

Now we can solve for 56 km..

56km=39370.1*56
56km= 2204725.6in

Answer=2,204,725.6in

Determine the values of m and n when the following mass of the Earth is written in scientific notation: 5,970,000,000,000,000,00

uysha [10]

Answer: 5.97, 24

m = 5.97

n = 24

SN = 5.97 × 10^24 kg

Explanation:

Scientific notation or standard form is a way of rewriting very large or very small (minute) numbers in conveniently in decimal form. The standard way of writing scientific notation is of the form;

m × 10^n

To derive m, we need to reduce it to a number between 1 and 10 ( 10 exclusive)

For the case above ;

m = 5.97

To get the value of n, we need to count the number of digits from the right egde of the data to the point where we put the decimal.

For the case above;

n = 24

Therefore, the scientific notation of the mass of the earth is ;

M = 5.97 × 10^24 kg
