Answer 1

Hope this helps you ☺☺

Answer 2

Answer:

892.61cm^2

Step-by-step explanation:

Given, height of the cylinder=7cm

Area of the base=250cm^2

We know that,

Area of the base=pir^2

$\pi {r}^{2}$

250=3.14×r^2

r=8.92cm

So,

Total surface area of the cylinder=2pir(r+h)

=2×22/7×8.92×(8.92+7)

=892.61cm^2

Hence, Total surface area of the cylinder=892.61cm^2
