Answer:
Step-by-step explanation:
According to the Question
It is given that,
we have to calculate the radius of its base and its volume .
(i) its radius of its base
As we know
On substituting the value we get
→ 94.2 = 2 × 3.14 × r × 5
→ 94.2 = 6.28 × r × 5
→ 94.2 = 31.4 × r
→ r = 94.2/31.4
→ r = 3 cm
(ii) its volume
As we know
On substituting the value we get
→ Volume of Cylinder = 3.14 × 3² × 5
→ Volume of Cylinder = 3.14 × 9 × 5
→ Volume of Cylinder = 3.14 × 45
→ Volume of Cylinder = 143.3 cm³
