Question

An 8cm long solid is in the form of a right circular cylinder. If its radius is 3.5 cm, then find the volume of the solid​

Answer 1

Answer:

Volume = 308 cm square

Step-by-step explanation:

Volume of cylinder=

$\pi \: r \times r \times h$

22/7×3.5×3.5×8

Answer 2

Answer:

Volume = $\pi r^2h$

r = 3.5 cm

h = 8cm

Volume =

$\pi r^2h\\= \frac{22}{7} \times 3.5 \times 3.5\\= 22 \times 0.5 \times 3.5\\= 38.5 \text{ cm}^2$
