Question

Find the volume of the following solid figures write your answer on your answer sheet use 3.14 for value of p i

plssss with solution I need it​

Answer 1

Answer: Question 4 =791.28m^3

Question 2 = 2260.80m^3

Question 5 = (rounded) 1716.80m^3

(not rounded) 1716.795m^3

Explanation:

Cone = V= 3.14(r)(r)(h)

3

Sphere = V= 3/4 (3.14)(r)(r)(r)

Cylinder = V= 3.14(r)(r)(h)

Answer 2

1) 1/3x bh
1/3 x 15x8x12
1/3x120x12
1/3x1440
=480cm^3

2) v=pi x r^2 x h
Pi x 6^2 x 20
3.14 x 6^2 x 20
113.04 x 20
= 2260.8cm^3

3) v=1/3 x bh
1/3 x 6 x 6 x 15
1/3 x 36 x 15
1/3 x 540
= 180 dm^3

4) v = 1/3 x pi x r^2 x h
1/3 x 3.14 x 6^2 x 21
1/3 x 113.04 x 21
1/3 x 2373.84
= 791.28 cm^3

5) v = 4/3 x pi x r^3
4/3 x 3.14 x 9^3
4/3 x 2289.06
=3052.08 cm^3
