olya-2409 [2.1K]

The second hand of a clock is 8 cm long what is the distance of the tip of the second hand travel in 10 minutes

<em><u>Answer:</u></em>

The distance travelled by tip of second hand in 10 minutes is 502.4 cm

<em><u>Solution:</u></em>

Length of second hand = 8 cm long

In one revolution it travels a circumference of  a circle of which radius is 8 cm

The circumference of circle = 2 \pi r

c = 2 \times \pi \times 8 = 16\pi

We are aksed to find the distance of the tip of the second hand travel in 10 minutes

Second hand complete 1 revolution in 1 minute.

Therefore, in 10 minutes it revolves 10 revolution,

In 1 revolution tip of second covers = 16π

<em><u>Hence distance travelled is given as:</u></em>

\rightarrow 16 \pi \times10 = 160 \pi

We know that π is a constant equals to 3.14

\rightarrow 160 \pi = 160 \times 3.14 = 502.4

Thus the distance travelled by tip of second hand in 10 minutes is 502.4 cm

Analyze the diagram below and complete the instructions that follow.

According to the image:
the right hexagonal pyramid surface area is given by the following formula:

S = 3√3 / 2) a² + 3a √h²+3a²/4
a = the base edge
h = the height of the pyramid

looking at the image  a =6m,  h =21m - 7m= 14m

so the surface area is S = 3√3 / 2) 6² + 3*6√14²+3*6²/4 =93.53+ 14.93=108.46 m²

for the another one
the figure is a prism hexagonal
its surface area is 
SA= 6ah +3√3 a²
a= base edge, h =height
in our case a =6m and h = 7m
so SA= 6*6*7 + 3√3 * 6²= 252 + 187 = 439 m²

finally, the surface area of the complete image is 
ST= S + SA = 108.46 m² + 439 m² = 547.52 m²
it is so approximate
 to <span>B. 615.53 m2
look at the image</span>

Answer:

400cm²

Step-by-step explanation:

the surface area of the sphere =

4/3 x The total surface area of a hemisphere

=> 4/3 x 300 = 400cm²

Ahh help plss!! thank u

Basically you’re multiplying them both
(x^3 + 2x - 1)(x^4 - x^3 + 3)

so you need to make sure you multiply each one, if you do it right, you should end up with
x^7 - x^6 + 3x^3 + 2x^5 - 2x^4 + 6x -x^4 +x^3 -3

simplify by adding like terms
x^7 - x^6 + 2x^5 - 3x^4 + 4x^3 + 6x - 3

your answer would be the third option
