Question

please give me correct answer

What is the difference between the total surface area
and curved surface area of a cylinder whose radius is
equal to 10 cm ?
(A) 2001 cm
(B) 3001 cm
(C) 1001 cm
(D) 107 cm​

Answer 1

Answer:

628 cm

Step-by-step explanation:

total surface area = tsa

curved surface area = csa

$tsa = (2 \times\pi \times r \times h) + (2 \times \pi \times {r}^{2} ) \\ csa = (2 \times \pi \times r \times h) \\ difference = 2 \times \pi \times {r}^{2}$

$= 2 \times \pi \times {10}^{2} \\ = 628.318$
