Question

please help me in math subject​

Answer 1

Answer:

904.32 cm³

40 dm³

440 dm³

1437.33 yd³

Step-by-step explanation:

1.

Volume of cylinder

$= \pi {r}^{2} h \\ = 3.14 \times (6 \times 6) \times 8 \\ = 904.32$

2. volume of prism

$= \frac{1}{3} \times b \times h \\ = \frac{1}{3} \times 12 \times 10 \\ = 4 \times 10 \\ = 40 \: {dm}^{3}$

3.volume of cone

$= \frac{1}{3} \times b \times h \\ = \frac{1}{3} \times 40 \times 33 \\ = 40 \times 11 \\ = 440 \: {dm}^{3}$

4. volume of sphere

$= \frac{4}{3} \times \pi \times {r}^{3} \\ = \frac{4}{3} \times \frac{22}{7} \times (7 \times 7 \times 7) \\ = \frac{4}{3} \times 22 \times 49 \\ = 1437.33 \: {yd}^{3} \\ (value \: of \: \pi = \frac{22}{7} )$
