The bases of a cylinder have a diameter of 4 inches. The height of the cylinder is 6 inches. What is the total surface area of the cylinder? A:251.2
B:100.53
C:163.28
D:87.92​

B: 100.53 in²

Step-by-step explanation:

Area is twice the area of the circular base plus the area of a rectangular side with height and circle circumference as dimensions

A = 2(πR²) + 2πRh = 2πR²(1 + h/R)

A = 2π2²(1 + 6/2) = 32π ≈ 100.53 in²

step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to

> by central angle

substitute the value
