Step-by-step explanation:
For this case we have that a percentage equivalent tois given by:
12.5%
Then, according to the steps, it is observed that Harriet made an incorrect division, deboa multiply. So, the second step is the wrong one.
Answer:
Option B
Answer:
a. 4r² b. 2r c. 6 cm
Step-by-step explanation:
The surface area A of the cube is A = 24r². We know that the surface area, A of a cube also equals A = 6L² where L is the length of its side.
Now, equating both expressions, 6L² = 24r²
dividing both sides by 6, we have
6L²/6 = 24r²/6
L² = 4r². Since the area of one face is L², the polynomial that determines the area of one face is A' = 4r².
b. Since L² = 4r² the rea of one face of the cube, taking square roots of both sides, we have
√L² = √4r²
L = 2r
So, the polynomial that represents the length of an edge of the cube is L = 2r
c. The length of an edge of the cube is L = 2r. When r = 3 cm.
L = 2r = 2 × 3 cm = 6 cm
So, the length of an edge of the cube is 6 cm.
Answer:
Area of circle is
Step-by-step explanation:
Since angle is given in radians, so using formula for area of sector in radians is given as,
Given area of sector and angle. Therefore substituting the values in above formula,
Cancelling out the common term,
Multiplying with 2 on both sides,
Therefore value of is
Formula for area of circle is,
Substituting the value,
Therefore area of circle is
