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

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)

If disposable income is $20 trillion, taxes are $6 trillion, and transfers are $4 trillion, then income is $_____ trillion. Plea

Serjik [45]

Answer:

c) $22 trillion.

Step-by-step explanation:

We have been given that disposable income is $20 trillion, taxes are $6 trillion, and transfers are $4 trillion. We are asked to find income in trillions.

$\text{Disposable income}=\text{Income}+\text{Transfers}-\text{Taxes}$

$\$20=\text{Income}+\$4-\$6$ , where each amount is in trillions.

$\$20=\text{Income}-\$2$

$\$20+\$2=\text{Income}-\$2+\$2$

$\$22=\text{Income}$

Therefore, the income is $22 trillion.

Yes because all sides would be equal to 5 which would give you 5*4 = 20 units.
