7 cm and height is
2 cm?(Volume = πr
2h)
c DA.
D96
π cm
3B.
D100
π cm
3C.
D98

3D.
Dnone of these
D
C
Step 1: The volume of a cylinder = πr2h[Formula.]
Step 2: = π × 72 × 2[Substitute r = 7 and h = 2.]
Step 3: = 98π cm 3[Simplify.]
Step 4: So, the volume of the cylinder that Johnny made is 98π cm 3.
