In the diagram, angle abc is a right angle. Find the value of x<br><br> Show full working out pls ty

Vladimir79 [104]

Answer:

x = 3.75

Step-by-step explanation:

ABC is a right angled triangle.

Therefore, by Pythagoras theorem:

${(10 - x)}^{2} = {x}^{2} + {5}^{2} \\ 100 - 20x + {x}^{2} = {x}^{2} + 25 \\ 100 - 20x = 25 \\ - 20x = 25 - 100 \\ - 20x = - 75 \\ x = \frac{ - 75}{ - 20} \\ \: \: \huge \red { \boxed{x = 3.75}}$

1. Find the volume for 5 different spheres by randomly choosing different radii.

Sophie [7]

The volume of the sphere is given by :

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

And volume of cylinder is given as :

V= $\pi r^{2}h$

So, as given to select the radius randomly and the height of the cylinder will be the diameter of the sphere.

The radius are = 3, 5, 8, 10, 12

And height will be = 6, 10, 16, 20, 24

1. Volume of sphere with radius 3 = $\frac{4}{3}*3.14*3*3*3= 113.04$ units

Volume of cylinder with radius 3 and height 6 = $3.14*3*3*6=169.56$ units

2. volume of sphere with radius 5 = 523.60 units

volume of cylinder with height 10 = 785.40 units

3. volume of sphere with radius 8 = 2144.66 units

volume of cylinder with height 16 = 3216.99 units

4. volume of sphere with radius 10 = 4188.79 units

volume of cylinder with height 20 = 6283.19 units

5. volume of sphere with radius 12 = 7238.23 units

volume of cylinder with height 24 = 10857.34 units
