471 cm

Step-by-step explanation:

Surface Area of Cylinder = 2πrh + 2πr^2

Since we are only finding the surface area on the outside of the cylinder, it’s just 2πrh

3.14 * 2 = 6.28

6.28 * 3 = 18.84

18.84 * 25 = 471

£56

step-by-step explanation:

u divide 24 by 3 and u get 8 so if u do 8 time 7 or 8+8+8+8+8+8+8 u get 56 and 56 divided by 7 is 8.

the answer will be b x² +x-1
