a square stained window is divided into four congurent traiangular sections by iron edging to represent seasons of the year. Eac
Norma-Jean [14]

Answer:

Total length of iron needed to make the square frame and two diagonals =  43.44 in (Approx)

Step-by-step explanation:

Given:

Length of diagonal = 9 in

Find:

Total length of iron needed to make the square frame and two diagonals.

Computation:

Area of square = 1/2(diagonal)²

Area of square = 1/2(9)²

Area of square = 40.5 in²

Area of square = Side × Side

40.5 in² = Side × Side

Side = 6.36 (approx)

Total length of iron needed to make the square frame and two diagonals = Permeter of square + (2 × diagonal)

⇒ (4 × 6.36) + (2 × 9)

⇒ (25.44) + (18)

⇒ 43.44 in

Total length of iron needed to make the square frame and two diagonals =  43.44 in (Approx)

What is the approximate radius of a sphere of volume 528 m³? round the answer to hundreth
makvit [3.9K]

\\ \sf\longmapsto V=\dfrac{4}{3}πr^3

\\ \sf\longmapsto 528=\dfrac{4}{3}πr^3

\\ \sf\longmapsto \pi r^3=528\times \dfrac{3}{4}

\\ \sf\longmapsto πr^3=32(3)

\\ \sf\longmapsto \pi r^3=96

\\ \sf\longmapsto 3.14r^3=96

\\ \sf\longmapsto r^3=\dfrac{96}{3.14}

\\ \sf\longmapsto r^3=30.57

\\ \sf\longmapsto r=3.09m=3.1m

HELP PLEASE I HAVE A TIME LIMIT

Using the Euler's formula, the number of segments in the pentagonal prism is: 15.

<h3>What is the Euler's Formula?</h3>

The Euler's formula is given as,  F + V = E + 2, where:

  • F = number of faces (number of regions)
  • V = vertices
  • E = number of edges (number of segments).

Given that the pentagonal prism has the following dimensions:

  • F = 7
  • V = 10
  • E = number of segments = ?

Plug in the values into the Euler's formula, F + V = E + 2:

7 + 10 = E + 2

17 - 2 = E

E = 15

Therefore, using the Euler's formula, the number of segments in the pentagonal prism is: 15.

Answer:

9.2*10^3

Step-by-step explanation:

to find the quotient you need to divide those numbers

8.832*10^6 / 9.6*10^2

= 8.832*10^4 / 9.6

= 0.92*10^4

= 9.2*10^-1+4

= 9.2*10^3
