Question

1) Find the total surface area and volume of the
following cylinder, given the radius and height..
(i) r=7.7 cm, h= 10 cm​

Answer 1

Answer:

130438/7

Step-by-step explanation:

volume of cylindre

$= \pi r {}^{2} h$

u

$\frac{22}{7} \times 7.7 \times 7.7 \times 10$

Answer 2

Answer:

radius of cylinder=77cm

height of cylinder=10cm

total surface area of cylinder=2πrh

=2×22/7×77×10

=2×11×11×1/5.

= 2×121×1/5. =242/5. =48.4cm2. , volume of cylinder=πr×r×h.

=22/7×77×77×10 = 11/5×11×77. = 9317/5. =1863.4 cm3
