Question

a bucket is in the form of a cylinder of radius 3.5cm and height 12cm. finf
a) the lateral surface area of the bucket
b) the total surface area, if top of the bucket is open​

Answer 1

$\huge\sf\red{Answer}$

Given :-

Radius of a cylinder = 3.5cm

Height of a cylinder = 12cm

Find :-

Lateral surface area of bucket

Total surface area of open bucket

Solution :-

Lateral surface area of cylinder = 2πrh

$2 \times \frac{22}{7} \times 3.5 \times 12$

$= 264cm^{2}$

Hence, The lateral surface area of bucket is 264cm²

Total Surface area of open cylinder = Lateral surface area + area of base or top

2πrh + πr²

πr(2h+r)

$\frac{22}{7} \times 3.5(2 \times 12 + 3.5)$

$\frac{22}{7} \times 87.5$

$= 275cm ^{2}$

Hence, The total surface area of open bucket is 275cm²
