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:

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:

No, I don't think so.

Step-by-step explanation:

If his suitcase weighs 23 kg and 10 kg is 22 pounds. You could seperate it. 10, 10, and 3 meaning 22+22= 44. This would mean that 1 kg would equal about 2.2 a pound. So 44 + ( 2.2 x 3 ) = 50.6 kg.

It would be 0.6 k.g over. I think this is right unless I calculated this wrong.

Andrew can not check his suitcase and it needs to remove some items or repack it in order to reduce the weight.

To measure and compare various things we use one term which is known as a unit.

For example, for  length measurement we use units like:- metre, centimetre, inch, miles.

To determine if Andre can check his suitcase, we need to convert the weight of his suitcase from kilograms to pounds since the weight limit for checked luggage is given in pounds.

Given that 10 kilograms ≈ 22 pounds, we can convert Andre's suitcase weight of 23 kilograms to pounds by multiplying it by the conversion factor:

23 kilograms x 22 pounds/kilogram ≈ 506 pounds

Therefore, Andre's suitcase weighs approximately 50.6 pounds, which exceeds the weight limit of 50 pounds.

Therefore, Andre cannot check his suitcase and needs to remove some items or repack it to reduce the weight below the weight limit.

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

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)

Answer:

C is 25

Step-by-step explanation:

Because 25+38=63 and 63/7 is equal to 9.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

The value of c in the expression (c + 38) / 7 = 9 is 25.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example:

2 + 3x + 4y = 7 is an expression.

(3x + 2)/ 3 is an expression.

2x + x + 4x is an expression.

We have,

(c + 38) / 7 = 9______(1)

We will solve for c.

From (1).

(c + 38) / 7 = 9
Multiply 7 on both sides.

7 x (c + 38) / 7 = 7 x  9

c + 38 = 63

Subtract 38 on both sides.

c + 38 - 38 = 63 - 38

c = 25

Thus,

The value of c in the expression (c + 38) / 7 = 9 is 25.

- 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:
