Volume of a cylinder is π * r^2 * h
so 3^2 * 7 * π = 9 * 7π = 63π cm^3

Answer:

Option (D) is correct.

The volume of given cylinder is 63π cm³

Step-by-step explanation:

Given : a cylinder with a radius of 3 cm and a height of 7 cm.

We have to find the volume of the given cylinder.

Consider the given cylinder with a radius of 3 cm and a height of 7 cm

We know,

Volume of cylinder = \pi r^2h

Where, r is radius

and h is height

Substitute, h = 7 and r = 3

We have,

Volume of cylinder = \pi \cdot (3)^2 \cdot 7

Simplify, we have,

Volume of cylinder = \pi \cdot 9 \cdot 7

Volume of cylinder = 63\pi

Thus, The volume of given cylinder is 63π cm³

Sven Hendriksson finds that one of his productivity measures is related to the number of employees, e, and the production, n, by
muminat

Answer:

n = 3

e = 5

Step-by-step explanation:

10n + 3e = 45

2n + 5e = 31

10n + 3e = 45

10n + 25e = 155

o + 22e = 110

e = 5

to fix 5 into the first equation

10n + 3(5) = 45

10n + 15 = 45

10n = 45 -15

10n = 30

n = 3

Prepare the journal entries on December 31, 2019, for the 40 extended contracts (the first year of the revised 3-year contract).
Pavel [41]

This is not the complete question, the complete question is:

P18-1 (LO2,3) (Allocate Transaction Price, Upfront Fees)

Tablet Tailors sells tablet PCs combined with Internet service, which permits the tablet to connect to the Internet anywhere and set up a Wi-Fi hot spot. It offers two bundles with the following terms.

1. Tablet Bundle A sells a tablet with 3 years of Internet service. The price for the tablet and a 3-year Internet connection service contract is $500. The standalone selling price of the tablet is $250 (the cost to Tablet Tailors is $175). Tablet Tailors sells the Internet access service independently for an upfront payment of $300. On January 2, 2017, Tablet Tailors signed 100 contracts, receiving a total of $50,000 in cash.

2. After 2 years of the 3-year contract, Tablet Tailors offers a modified contract and extension incentive. The extended contract services are similar to those provided in the first 2 years of the contract. Signing the extension and paying $90 (which equals the standalone selling of the revised Internet service package) extends access for 2 more years of Internet connection. Forty Tablet Bundle A customers sign up for this offer.

INSTRUCTION

a) Prepare the journal entries when the contract is signed on January 2, 2019, for the 40 extended contracts. Assume the modification does not result in a separate performance obligation.

b) Prepare the journal entries on December 31, 2019, for the 40 extended contracts (the first year of the revised 3-year contract).

Answer:

Step-by-step explanation:

(A)

Date        Particulars                               Debit                     Credit

2-Jan-19        Cash                                        3600  

                      Unearned Service Revenue                               3600

40 * 90 = 3600

services in the extended period are the same as the services that were provided in the original contract period. As they are not distinct hence the modifications will be considered as part of the original contract.

(B)

Date           Particulars                                    Debit           Credit

31-Dec-19 Unearned Service Revenue            2413  

                       Service revenue                                             2413

internet = 300, price = 550, connection service = 500

(300/550) * 500 = 273

so

Original internet service contract = 40 * 273 = 10,920

Revenue recognized in 1st two years = 10,920 * 2/3 = 7280

Remaining service at original rates = 10920 - 7280 = 3640

Extended service = 3600

3640 + 3600 = $7240  

7240 / 3 = $2413
