Answer:
A = 78.54 cm^2
C = 31.42 cm
Step-by-step explanation:
A = πr^2
A = π (5cm)^2
A = 25π cm^2
A = 78.54 cm^2
C = 2πr
C = 2π(5cm)
C = 10π cm
C = 31.42 cm

Answer:
9pi meters^2
Step-by-step explanation:
The area of a circle is pi * r^2. Basically, pi is simplified to 3.14 but for an exact answer, you'd leave it as a symbol. the "r" stands for the radius which is given(3). we square 3 to get 9. so the answer should be 9 pi or about 28.26.

Concept 9.3: Find the value of x in the circle.
Answer:
x=4.5
Step-by-step explanation:
MAB=MBC
AB=BC
3x+2=5x-7
7+2=5x-3x
9=2x
x=9/2
x=4.5
hope it helps..
have a great day!!
Answer:
x = 4.5
Step-by-step explanation:
here's your solution
=> AB = BC. ( both arc are equal )
=> 3x + 2 = 5x - 7
=> 3x - 5x = - 7 - 2
=> - 2x = - 9
=> x = 9/2
=> x = 4.5

Find the area of the sector. Use 3.14 for the value of 5. Round your answer to the nearest tenth.
Answer:
12.56m^2
Step-by-step explanation:
a = piR^2
The area of a sector of a given circle is 37.7 m².
Given that, the radius of a circle=4 m and the central angle of a circle=270°.
What is the formula to find the area of a sector?The area of a sector is the space inside the section of the circle created by two radii and an arc. It is a fraction of the area of the entire circle.
The formula to find the area of a sector is θ/360°(πr²).
Where r is the radius of the circle and θ is the angle of the sector.
Now, area=270°/360°(3.14×4×4)=37.68≈37.7 m².
Therefore, the area of a sector of a given circle is 37.7 m².

(c) Rashid has 210g of cocoa powder and plenty of the other ingredients.
He says that he can make at least 75 cupcakes.
Is he correct?
Explain your reasoning.
Answer:
He is incorrect. He would need 225g of cocoa powder
Step-by-step explanation:
1. Lets calculate how much powder do we need per one cupcake, so 60 divided by 20, since 60g makes 20 cupcakes, 60/20 = we get 3g of cocoa powder per one cupcake.
2. Now we can multiply that by 75, 75*3=225, and 225g is more than 210g

Step-by-step explanation:
Write the equation of the circle with a center of (-5, 3) and a radius of 4.
A
(x + 5)2 + (y - 3)2 = 4
B
(x - 5)2 + (y + 3)2 = 4
(X - 5)2 + (y + 3)2 = 16
D
(x + 5)2 + (y - 3)2 = 16
Answer:
C
Step-by-step explanation:
Answer:
D
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
Here (h, k ) = (- 5, 3 ) and r = 4 , then
(x - (- 5))² + (y - 3)² = 4² , that is
(x + 5)² + (y - 3)² = 16 → D

Answer:
50 Degrees
Step-by-step explanation:
Since they already have 40 degrees for you, and a little square means a right angle (90 Degrees), then 40 + 90 is 130. The interior angles of a triangle always add up to 180, so 180 - 130 is 50. The answer is therefore 50 degrees.

What is a circle?A circle is a collection of all points in a plane which are at a constant distance from a fixed point. A circle is a round-shaped figure that has no corners or edges.
For the given situation,
In the figure, GB and GD are the secants of the circle.
In circle, intercept two arcs such that the measure of the angle that the segments form is equal to one-half the difference of the measures of the intercepted arcs. Thus arc length can be found as
[tex]\frac{1}{2}(mBD-mFE)=m \angle BGD[/tex] -------- (1)
Here, BD = [tex]35+100[/tex]
⇒ [tex]135[/tex]
FE = [tex]x[/tex]
m∠BGD = 55°
Now, equation 1 becomes
⇒ [tex]\frac{1}{2}(135-x)=55[/tex]
⇒ [tex](135-x)=55(2)[/tex]
⇒ [tex]135-x=110[/tex]
⇒ [tex]x=135-110[/tex]
⇒ [tex]x=25[/tex]
Hence we can conclude that the value of measure of arc FE is 25°.

Competency: Write the linear equations Ax + By = C. Give the value of A,B, and C,.
Answer:
see explanation
Step-by-step explanation:
(1)
y = - x + 4 ( add x to both sides )
x + y = 4
with A = 1, B = 1, C = 4
(2)
y = 5x + 7 ( subtract y from both sides )
0 = 5x - y + 7 ( subtract 7 from both sides )
- 7 = 5x - y , that is
5x - y = - 7
with A = 5, B = - 1, C = - 7
----------------------------------------------------------
(1)
2x + y = 9 ( subtract 2x from both sides )
y = - 2x + 9
with m = - 2, c = 9
(2)
5x + 2y = 7 ( subtract 5x from both sides )
2y = - 5x + 7 ( divide terms by 2 )
y = - [tex]\frac{5}{2}[/tex] x + [tex]\frac{7}{2}[/tex]
with m = - [tex]\frac{5}{2}[/tex] , c = [tex]\frac{7}{2}[/tex]
