Find the volume of the solid where the cone and half sphere are hollow. Use 3.14 for П ; height is 19 in; radius is 5 in. Round
Vera_Pavlovna [14]

Volume of Solids

The volume of the solid is 758.83 in³

Step-by-step explanation:

Given that the cone and half sphere is hollow

The volume of the cone = 1/3 \pi r^{2} h\\

The Volume of the sphere  = 4/3 \pi r^{3}

So the Volume of the half sphere =2/3\pi r^{3}

The volume of solid = volume of cone + volume of the half sphere

V = V_{1}  + V_{2}

Given

height h = 19 in

radius r = 5 in

V_{1\\}  = 1/3 \pi r^{2} h

     = 1/3 × 3.14 × 5 × 5 × 19

     = 497.16 in³

V_{2}  =  2/3 \pi r^{3}

   = 2/3 × 3.14 × 5 × 5 × 5

   = 261.67 in³

V =  497.16 in³ + 261.67 in³

  = 758.83 in³

Hence the volume of the solid is 758.83 in³

At the start of 2014 Lucy's house was worth £200000. The value of the house increased by 5% every year. Work out the value of he
Annette [7]

Answer:

231,525

Step-by-step explanation:

At the start of 2014 it was worth 200,000

At the start of 2015 it was worth 200,000 plus the 5% of the 2014 worth

5% of 200,000 is 10,000

So at the star of 2015 the worth was (200,000 + 10000) = 210,000

In 2016 the worth was 210,000 plus 5% of it

The 2016's worth was (210,000 + 10500) = 220,500

The 2017's worth was 220,500 plus 5% of it

The 2017's worth was (220,500 + 11,025) = 231,525
