I don’t know what to do. Can you please help me.
konstantin123 [22]

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)

A cone has a slant length of 10 and a diameter of 8. Height is unknown.
patriot [66]

Answer: 153.56

Step-by-step explanation:

Hi, to answer this question we have to apply the next formulas:

Volume of a cone: 1/3 π r² h

Where r is the radius and h is the height (unknown)

Diameter = r x 2

8 = 2r

8/2 =r

r = 4  

Before calculating the volume we have to apply the Pythagorean Theorem to find h. (where the slant is the hypotenuse and h and r are the sides of the triangle)

10 ² = h² + 4²

Solving for h

100 = h² + 16

100-16 = h²

84= h²  

√84 =h

9.16= h

Back on the volume formula:

V= 1/3 π r² h

V =1/3 π 4² (9.16) =153.56
