Answer:
<u>2 </u>sack of cement is required to cover Joel's entire floor.
Step-by-step explanation:
Given:
A sack cement can cover area = 45 sq. ft
Length of Joel floor = 8 ft
Width of Joel Floor = 7 ft
We will first find the Area of Joel's Floor
Area is the Product of length and width.
Area of the Floor =
Substituting the values we get;
Area of the Floor =
Now Given:
1 sack of cement cover area = 45 sq ft
Number of sack cement required to cover area = 56 sq. ft.
By Using Unitary method we will find the same.
∴ Number of sack cement required =
Since Sack of cement cannot be in point value hence we can say 2 sack cement is required.
Hence we can say 2 sack of cement is required to cover Joel's entire floor.
Answer:
8 ft; 6 m; 28pi ft; 10pi mm
Step-by-step explanation:
1. Radius = diameter/2
16/2=8
Therefore, 8 ft
2. Diameter= radius * 2
3*2=6
Therefore, 6 m
3. Circumference = 2*pi*r
2*pi*14=28pi
Therefore, 28pi ft
4. Circumference = pi*d
Therefore, 10pi mm
I hope this helped and have a good rest of your day!
Answer:
Step-by-step explanation:
<u>Trigonometric Identities</u>
<u>Trigonometric ratios</u>
where:
- is the angle
- O is the side opposite the angle
- A is the side adjacent the angle
- H is the hypotenuse (the side opposite the right angle)
Using the trig ratio formulas for cosine and sine:
Therefore, using the trig identities and ratios:
