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)

lidiya [134]

Answer:

4.8 hours

Step-by-step explanation:

Distance = speed × time

If Tim drove 4 hours at 60 miles per hour

Than he drove a total of 4×60 miles

He drove 240 miles

Time = distance ÷ speed

If he drove 240 miles at 50 miles per hour

Than he took 240÷50 hours

He took 4.8 hours (4 hours and 48 minutes)

Find the area of each figure. Round to the nearest hundredth if needed.
Hitman42 [59]

Answer:

<h3>#1</h3>

<u>Trapezoid</u>

  • A = (b₁ + b₂)h/2
  • A = (4.8 yd + 29.4 ft)(8 yd)/2 = (14.6 yd)(4 yd) = 58.4 yd²
<h3>#2</h3>

<u>Rectangle</u>

  • A = ab
  • A = 2 yd * 3.1 yd = 6.2 yd²
<h3>#3</h3>

<u>Equilateral triangle</u>

  • A = √3/4a²
  • A = √3/4(10²) = 25√3
<h3>#4</h3>

<u>Regular octagon</u>

  • A = aP/2
  • A = 14.5(12*8)/2 = 696
