When the ratio is 1:1, either is 1/(1+1) = 1/2 the total.
Answer:
B. 3
It says the answer is too short so im just typing random stuff
Answer:
one-sixth
multiply the numerator (2) by the number of kids (3) because you are accounting for the fraction of the whole pizza. By doing this you should get 3/6. divide the denominator by the number of kids (3/3) getting you to a value of 1, and replace the denominator, making the amount of pizza one-sixth.
Answer:
area = 39.25 cm²
Step-by-step explanation:
The top and bottom area of a cheese wedge is shaped like a sector of a circle so finding the area of the top surface of this wedge is same as applying the area of a sector.
Top surface area(sector) = ∅/360 × πr²
where
∅ = central angle
r = radius
Top surface area(sector) = ∅/360 × πr²
area = 45/360 × π × 10²
area = 1/8 × 100π
area = 100π/8
area = 100 × 3.14/8
area = 314
/8
area = 39.25 cm²
Answer:
R= 20.88 ft
Step-by-step explanation:
See the diagram attached, this satisfies the condition, ΔKLM is enclosed in a circle of radius R.
LN=16 ft (given)
The value of KM is 2R because as the ∠KLM forms an angle of 90°, therefore, the line KM passes through the center.
Area of a triangle = ![\frac{1}{2} * Base * Height](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%20%2A%20Base%20%2A%20Height)
Now let's find he area of the ΔKLM=![\frac{1}{2} * KM * LN](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%20%2A%20KM%20%2A%20LN)
= ![\frac{1}{2} * 2R* 16\\\\=16R](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%20%2A%202R%2A%2016%5C%5C%5C%5C%3D16R)
Also the area can be found out by =
( As KLM is a right angled triangle)
KL= KM cos 25°= 2R cos 25°
LM= KM cos 55°= 2R sin 25°
Area=
x 2R cos 25°x 2R sin 25 °
=
sin 50°
sin 50°= 16R
R sin 50°=16
R= 20.88 ft
