Find the total surface area of a cylinder with a height of 7 cm and radius of 3 cm. Leave your answer in terms of π.
140π cm2
91π cm2
60π cm2
51π cm2

=60π cm2

Step-by-step explanation:

Total surface area of a cylinder is calculated by 2πrh+2πr2, where π is a constant, h is the height= 7cm and r is radius= 3cm

Slot the values into the formula:

2π(3 × 7 ) + 2π (3)^2

2 π 21 + 2π9multiply 2 by 21, and 2 by 9

42π + 18π

=60π cm2

I hope this helps.

Option C.60π cm2 is the correct answer for this .

step-by-step explanation:

to determine whether a given function is even, we simply substitute x with -x in the expression. if the result after simplification is identical to the original equation, then the function is said to be even other wise odd.

f(-x) = (-x)^2 - (-x) + 8

      = x^2 + x +8

the resulting function is not identical to the original one;

f(-x) ≠ f(x)

therefore, f(x) is not an even function
