Question

The volume of a cylindrical bucket is 660cm3 and its height is 11cm.
Find out the area of the base of the bucket. ​

Answer 1

Answer:

volume = area × height

660cm³ = area× 11cm

area = 660/11 cm²

area = 60 cm²

Answer 2

Step-by-step explanation:

method 1 :

Vol = Area of base × height

660 = 11× area

660/11 = area

60cm² = area of base.

method 2:

Volume of Cylinder = πr²h

660= πr²×11

$\frac{660}{11} = \pi \: r {}^{2} \\ 60 = \pi \: r {}^{2} = \frac{22}{7} r {}^{2} \\ \frac{60 \times 7}{22} = r {}^{2} \\ \sqrt{ \frac{420}{22} } = r = 4.37cm$

Area = πr²= π × 420/22

area = (22× 420 )/ (7×22) = 60cm²
