Step-by-step explanation:
Answer:
<em><u>10 cm</u></em>
Explanation:
Surface area of cube = 600 cm^2
Side of a cube = ?
Formula:
Total S.A of cube = 6 x (side of cube)^2
= 6 . x^2
600 cm2 = 6 . x^2
x^2 = 600 / 6
x^2 = 100
x = 10 cm
<em>The required side of a cube = 10 cm</em>
Answer:
22 11/16 or 22.68
Step-by-step explanation:
Turn the mixed numbers to fractions
![\frac{11}{2} *\frac{33}{8}](https://tex.z-dn.net/?f=%5Cfrac%7B11%7D%7B2%7D%20%2A%5Cfrac%7B33%7D%7B8%7D)
Then multiply both Numerators
11 x 33=363
Also do the same to the Denominators
2 x 8=16
You get ![\frac{363}{16}](https://tex.z-dn.net/?f=%5Cfrac%7B363%7D%7B16%7D)
Simplify and it becomes 22 11/16 or 22.68
Answer:
"Let's say it is equal to 45 degrees, or π/4. Calculate the arc length according to the formula above: L = r * Θ = 15 * π/4 = 11.78 cm . Calculate the area of a sector: A = r² * Θ / 2 = 15² * π/4 / 2 = 88.36 cm² . You can also use the arc length calculator to find the central angle or the radius of the circle. "
Answer:
No, the correct answer is 13/45
Step-by-step explanation:
Find the greatest common factor and change the equations
8/9 -> 40/45
3/5 -> 27/45
40/45 - 27/45 = 13/45
13/45 is the correct answer
