Question

Find the volume of the sphere whose radius is :
(1) 6 cm (π = 3.14)
(2) 7 cm
(3) 10.5 cm
PLEASE TELL ME NAME OF THE BOOK OF THIS QUESTION​

Answer 1

Step-by-step explanation:

Volume of sphere =4/3(π×r×r×r)

(1). r=6cm

volume of sphere==4/3(π×r×r×r)

=4/3(3.14×6×6×6)

=2712.96÷3

=904.32cm^3.

(cm^3=cm×cm×cm)

(2). r=7cm

volume of sphere==4/3(π×r×r×r)

=4/3(3.14×7×7×7)

=4308.08÷3

=1436.02cm^3

(cm^3=cm×cm×cm)

(3). r =10.5cm

volume of sphere=4/3(π×r×r×r)

=4/3(3.14×10.5×10.5×10.5)

=14539.77÷3

=4846.59cm^3

(cm^3=cm×cm×cm)
