Question

find the total surface area and volume of the cylinder if area of the base is 346.5cm^2 and height is 24.5cm



I want it fully explain not the diert answer please don't answer hii or etc.or i will report it it ...​

Answer 1

Answer:

Step-by-step explanation:

As we know that :

Area of base = πr²

Given that,

the base area is 346.5cm²

Then,

⟾ 22/7 × r² = 346.5cm

⟾ r² = 346.5 × 7/22

⟾ r² = 110.25

⟾ r² = √110.25

⟾ r = 10.5cm

Now we have to find the total surface area of right circular cylinder

As we know that

Total surface area of right circular cylinder = 2πrh + 2πr²

⟾ 2 × 22/7 × 10.5 × 24.5 + 2 × 22/7 × 10.5 × 10.5

⟾ 2310 cm²


Area Of Base = 346.5 cm²

Height  = 24.5 cm

πr² = 346.5 ( as base is circular)

r²=346.5/π

volume = 1/3πr²h

⟾ 1/3π ×346.5/π × 24.5

⟾ 2829.75

Hope it helps you,
Have a great day
