Answer: 62.8cm^2

Step-by-step explanation:

The surface area of a cylinder is calculated by 2πrh+2πr2

where π is a constant, given as 3.14; h is the height, given as 3cm and r is radius, given as 2cm.

Therefore, rh = 3 x 2= 6 cm ^2 while r^2 =2 × 2= 4 cm^2.

Slot the values into the formula:

V= 2 (3.14) x 6 + 2 (3.14) x 4

V=37.68 + 25.12

V=62.8cm ^2

I hope this helps

Determine the 28th term of the sequence -242, -251, -260
maxonik [38]
We can figure this out using the explicit formula.
f(n)=f(1)+d(n-1)
n represents the term we are looking for.f(1) represents the first term in the sequence, which in this case, is -242.d represents the common difference, which in this case, is -9.

f(n) = -242 + -9(n - 1)
f(n) = -242 - 9n + 9
f(n) = -233 - 9n

Now, we can input 28 for n and solve.

f(28) = -233 - 9(28)
f(28) = -233 - 252
f(28) = -485

The 28th term of the sequence is -485.
