Answer:
66.67 %
Step-by-step explanation:
The surface area of a cake (cylinder) = 2πr² + 2πrh
but since we are not including bottom for chocolate cake so the formula changes to = 2ℎ+²
<h3>
S.A of cake </h3>
πr² + 2πrh
π4² + 2π(4)(4)
16π + 32π
48π inches
<h3>
S.A of chocolate</h3>
2ℎ+²(top)
24(2) + (4)²
16 + 16
32 inches
Percentage of cake that is chocolate = S.A of chocolate/S.A of cake * 100%
Percentage of cake that is chocolate = 32 inches/48π inches * 100%
Percentage of cake that is chocolate = 66.67%
(Assuming that top of chocolate is included)
