Answer:

602.88

Step-by-step explanation:

The two lids

Area = pi * r^2

d = 12

r = d/2

r = 12/2

r = 6 cm

Area = 3.14 * 6^2

Area = 3.14 * 36

Area = 113.04

Both Lids = 226.08

Cylinder Body

Circumference = 2*pi*r*h

Circumference = 2*3.14 *6 * 10 <u> 376.8</u>

Total Area = 602.88

Q is directly proportional to √p Q = 21 when p = 9, the value of Q when p = 81 is *

slavikrds [6]

Answer:

We get Q=63 when p=81

Option A is correct.

Step-by-step explanation:

We are given that $Q \propto \sqrt{p}$

We can write it as $Q=k\sqrt{p}$

Where k is constant of proportionality.

We are given Q = 21 when p = 9

Using this Q = 21 when p = 9 we can find value of k

$Q=k\sqrt{p}\\k=\frac{Q}{\sqrt{p} }\\k=\frac{21}{\sqrt{9} } \\k=\frac{21}{3}\\k=7$

So, we get constant of proportionality k = 7

Now, Finding the value of Q when p = 81

We are given p=81, k=7, we need to find Q

Using the equation $Q=k\sqrt{p}$ we can find value of Q.

$Q=k\sqrt{p}\\Q=7\sqrt{81}\\Q=7\times 9\\Q=63$

So, we get Q=63 when p=81

Option A is correct.

What is the simplified value of the expression -2.6+5.8

solniwko [45]

Answer:

[See Below]

Step-by-step explanation:

✦ Solve:

✧ -2.6 + 5.8 = 3.2

✦ Sometimes in math simplify could mean just solve and get the smallest version of that number. That's what it means in this case. So the simplified version would be 3.2.

On March 1, 2022, Carla Vista Co. acquired real estate, on which it planned to construct a small office building, by paying $79,

const2013 [10]

Answer:

Cost of the land = $90,900

Step-by-step explanation:

Cash Paid for the construction = $79,000

Cost of demolition of the old warehouse = $8,000

Salvage (i.e Proceeds from the salvaged materials) = $1,660

Additional Expenditure before construction began

Attorney's fee = $1,160

Real estate broker's fee = $4,400

Architect's fee = $8,660 ( Note that this will be capitalized to building cost)

Driveways and parking lot = $13,800 ( Note that this is capitalized to land improvements)

Sum of additional expenditure = Attorney's fee + Real estate broker's fee

Sum of the additional expenditure = 1160 + 4400

Sum of the additional expenditure = $5,560

Cost of the land = Cash paid + cost of demolition + Additional expenditure - salvage

Cost of the land = 79000 + 8000 + 5560 - 1660

Cost of the land = $90,900
