Answer:

The surface area of the cone is;

68 π m^2

Step-by-step explanation:

Here, we want to get the surface area of the cone

Mathematically, we have this as ;

S.A = π(r^2 + rl)

where r is the radius and l is the slant height

We are given the diameter, but the radius is half of this

d = 8

r = d/2 = 8/2 = 4 m

l = 13 m

S.A = π(4^2 + 4(13))

= π(16 + 52) = 68 π m^2

Answer:

Step-by-step explanation:

4^3 π = 64π units^2

64π unit² is the surface area of the sphere which is correct answer Option(A).

The formula for the surface area of a sphere of radius R is 4πR²

According to question, we have the radius of sphere as 4 units.

So, surface area of a sphere

⇒4πR²

⇒4π(4)²

⇒64π

Hence, the surface area of the sphere is 64π unit².

Answer:

r = 19 ft

Step-by-step explanation:

Circumference, C is given as 119.32 ft

Circumference of a circle is given by the formula, 2πr

This means that,

C = 2πr, we're told to assume that π = 3.14

So therefore,

119.32 = 2 * 3.14 * r

r = 119.32 / 6.28

r = 19 ft

Answer and Step-by-step explanation:

The answer is 42°.

This is because we are given an Isosceles Triangle. Isosceles Triangles always have 2 legs/sides that are the same length, and because those two sides have the same length, it means their base angles have the same value as well.

So, Since the angles LKM and KML are the base pairs of this Isosceles Triangle, they are equal to each other.

Step-by-step explanation:

1 dozen = 12 pears

12 pears = $36

1 pear = 36/12 = $3

Total Cost of Pears = No. of pears x price of 1 pear

= (5x12) x 3

= 60 x 3

= $180

Sale of Pears = Price per pear x (Total Pears bought - Rotten Pears)

= $4.50 x (5x12-7)

= $4.50 x 53

= $238.50

Profit/Loss = Sale of Pears - Total Cost of Pears

= $238.50 - $180

= $58.50

Ariana made a profit of $58.50.

Answer:

$58.5 (profit)

Step-by-step explanation:

Ariana bought 5 dozen pears at $36 per dozen.

The value of 1 dozen = $ 36

Her buying amount = $36 * 5 = $180

The value of 1 pear = $ 36/12

= $3

The value of 7 pears=  $3 * 7 = $21

She sold the remaining (53) at $4.50 each.

Her, selling amount = $4.50 * 53

= $238.50

Her profit amount = selling amount - buying amount

= $238.50 - $180

= $58.5

Answer:

4x² + 4x + 8

Step-by-step explanation:

P = 2( 2x² - 3x + 1 ) + 2( 5x + 3 ) = 4x² - 6x + 2 + 10x + 6 = 4x² + 4x + 8

4x² + 4x + 8

Answer:

4x^2 + 4x + 8.

Step-by-step explanation:

Perimeter = 2(width + length)

= 2(5x + 3 + 2x^2 - 3x + 1)

= 2(2x^2 + 2x + 4

= 4x^2 + 4x + 8.

Answer:

Step-by-step explanation:

Correct choice is D

[tex]\frac{\sqrt[4]{3x^2}}{2y}[/tex]  is the simplification of the given expression.

Simplifying procedures is one way to achieve uniformity in job efforts, expenses, and time. It reduces diversity and variation that is pointless, harmful, or unneeded. Parenthesis, exponents, multiplication, division, addition, and subtraction are called PEMDAS. The order of the letters in PEMDAS informs you what to calculate first, second, third, and so on, until the computation is finished, given two or more operations in a single statement.

It is given an expression [tex]\sqrt[4]{\frac{24x^6y}{128x^4y^5} }[/tex]

Simplifying the given expression using the PEMDAS technique,

[tex]\sqrt[4]{\frac{24x^6y}{128x^4y^5} }\\\\\sqrt[4]{\frac{3x^2}{16y^4} }\\\\\frac{\sqrt[4]{3x^2}}{2y}[/tex]

Therefore, the simplified value of the given expression is [tex]\frac{\sqrt[4]{3x^2}}{2y}[/tex]. Thus, the option D is correct.

Answer:

41.11m

Step-by-step explanation:

You're looking for the hypotenuse of a right triangle, so you'll use the pythagorean theorem of a^2 + b^2 = c^2. And here, you're looking for c^2

(18)(18) + (36)(36) = c^2

324 + 1296 = c^2

1690 = c^2

c = square root of 1690 = 41.1096095, round to 41.11

A = pi • 8^2

Step-by-step explanation:

The formula for area of a circle as A = pi • r^2. Radius is half the diameter, and the given diameter is 16 - therefore, the radius is 8. You then have to raise it to the second power and multiply it by pi to get the area of the circle. Hope this helped! Best of luck.

Answer:

The ameliorated retort, concerning the contemporaneous presented interrogate, is equated to an equation equivalence of B. A= π * 8^2

Step-by-step explanation:

To convey the ideology and retort proposed, the imminent is evaluated.

- To commence, the beginning of the interrogate states the figure obtains a diameter configuration of 16 inches.

- In addition, the radius, given which the diameter is equivalent to such, is obligated to equal 8 inches (r = 1/2(d)).

Furthermore, the precedent may be equated as the following:

A=πr^2

A= π * 8^2, whom is expressed to the unit of A = π * 64

Alas, in conclusion, the voracious retort, subject to the interrogate is equivalent to A = π * 8^2, A = π * 64, or "B."

Answer:

X = 3, Y = 1.

Step-by-step explanation:

X = 3 and Y = 1, because 2 times 3 equals 6, and 6 plus 1 equals 7. So that's for the first one, but now we need to make sure that it's the same value for the other equation. 3 times 3 equals 9, 4 times 1 equals 4, and 9 minus 4 equals 5. So X = 3, and Y =  1. Hope this helped :D

Answer:

5319

Step-by-step explanation:

There are two ways that the answer can be determined

Method 1

0.1 x 5710 = 571

5710 - 571 = 5319

Method 2

If the plants planted this year are 10% fewer, the plants this year are (100% - 10%) 90% of last year's plant

90% x 5710

0.9 x 5710 = 5319
