The area outside of the doghouse in which the dog can play is 16π m².
Thus, option (B) is correct.
Given:
The leash is 4 m long.
The doghouse is a 2 m × 2 m square.
First, the area of a square is given by side length squared
So, the area of the doghouse is:
Area of the doghouse = side length² = 2²
= 4 m².
Next, the area of the circle with a radius of 4 m.
The area of a circle is given by the formula A = πr²,
So, Area of the circle = π(4²) = 16π m².
Therefore, the area is 16π m².
Thus, option (B) is correct.

What is the surface area of the cylinder with height 7 cm and radius 3 cm? Round your answer to the nearest thousandth.
Answer:
188.52cm^2
Step-by-step explanation:
Given data
Height= 7cm
Radius= 3cm
The expression for the surface area of a cylinder is given as
Surface area= 2πr (h + r)
Surface area= 2*π*3 (7 + 3)
Surface area = 6π (10)
Surface area= 60*3.142
Surface area= 188.52cm^2

Answer:
Step-by-step explanation:
r = 3 km
Ф = 90°
Area of a sector = [tex]\frac{theta}{360}*\pi *r^{2}[/tex]
[tex]= \frac{90}{360}* 3.14 * 3 * 3\\\\= \frac{3.14*3*3}{4}\\[/tex]

The equation of a line given two points needs to be found. Samuel claims that slope-intercept form will generate the equation and Helena claims that point-slope form will find the equation. Who is correct?
Answer:
Helena is correct.
Step-by-step explanation:
The slope intersept form of the line is
y = m x + c
where, m is the slope and c is the intersept.
The point slope form of the equation is
[tex]y - y'= \frac{y''-y'}{x''-x'}\times (x-x')[/tex]
So, if there are two points are given, the equation of line is found by the point slope form.
So, Helena is correct.

Find the final price of a $849.99
laptop with 6% sales tax.
Answer:
$900.9
Step-by-step explanation:
Find the final price of a $849.99
laptop with 6% sales tax.
Given data
Price= $849.99
Tax = 6%
Let us find the amount of the tax
=6/100*849.99

At a sale on winter clothing, Cody bought four pairs of gloves and four hats for $36.00. Tori bought three pairs of gloves and four hats for $31.00. What were the prices for the gloves and hats?
Answer:
gloves cost $5
hats cost $4
Step-by-step explanation:
four pairs of gloves and four hats for $36.00
4g + 4h = 36
three pairs of gloves and four hats for $31.00
3g + 4h = 31
-------------------------
Subtract the second equation from the first
4g + 4h = 36
-( 3g + 4h = 31 )
––––––––––––
g = 5
gloves cost $5
substitute for g = 5 into either equation
4(5) + 4h = 36
20 + 4h = 36
Subtract 20 from both sides
4h = 16
Divide both sides by 4
h = 4
hats cost $4
Giving brainly help find Find m∠H.
The required measure of the angle m∠H is given as 94°.
What are the angle?Orientation of the one line with respect to the horizontal or other respective line is known as a measure of orientation and this measure is known as the angle.
Here,
For trapezoid, the sum of the adjacent angle is 180°
m∠H + m∠G = 180
5x + 26 + 8x - 2 = 180
x = 12
Now,
m∠H = 8x - 2
= 8 (12) - 2
= 94°
Thus, the required measure of the angle m∠H is given as 94°.

Maria tutors history. For each hour that she tutors, she earns 20 dollars. Her earnings, E (in dollars), after tutoring for h hours is given by the following.
E=20h
How much does Maria earn if she tutors for 5 hours?
Answer:
Maria earns 100 dollars
E=100
Step-by-step explanation:
if E=20h and they want to know how much Maria will make in 5 hours substitute the h for 5. 20 x 5 =100
E=100
Answer:
100
Step-by-step explanation:
The equation is E=20h
E is the amount she earns.
20 is the amount of money she earns per hour.
h is the amount of hours she worked.
She worked 5 hours. h represents hours so plug in 5 where h is in the equation.
E=20h
E=20(5)
E= 20×5
E=100

f(x) = x² , g(x) = x+1 find gof (2) , fog (2)
Answer:
Explanation:
Hey there!
Here;
f(X) = x²
and g(X) = X+1
To find: gof (2) and fog (2)
For gof (2),
gof = g{f(X)}
= g (x²)
= x²+1
Then;
gof(2) = 2²+1
= 4+1
= 5
Therefore, gof (2) is 5.
For fog(2),
fog (X) = f{g(X)}
= f(X+1)
= (x+1)²
= x²+2x+1
= x²+2x +1
Then;
fog(2) = 2²+2*2+1
= 4+4+1
= 9
Therefore, fog(2) = 9.
