Assuming that the units are in cm
Given,
Diameter of the cone = 12 cm
Using the above, the radius of the cone can be determined, which is half the diameter of the cone
∴ Radius of the cone (r) = 12/2 = 6 cm
Height of the cone (h) = 7 cm
Using the above, slant height (s) = √(r² + h²) = √(6² + 7²) = √36 + 49 = √85 = 9.22 cm
π = 3.14
Now using the above values, we can calculate the total surface area of the cone.
Total surface area of the cone (A) = Lateral surface area of the cone (L) + Base surface area of the cone (B)
Lateral surface area of the cone (L) = π r s = 3.14 x 6 x 9.22 = 173.70 cm²
Base surface area of the cone (B) = π r² = 3.14 x 6² = 113.04 cm²
Total surface area of the cone = L + B = 173.70 + 113.04 = 286.74 cm²
Answer:
55-45=10 it's 10$ discount
Step-by-step explanation:
f(x, y) = 4x + 7y - 6
substitute x=5 and y=-5
f(5,-5) = 4(5) + 7(-5) - 6
f(5,-5) =20-35-6
= -15-6
=-21
The area of the blue rectangle is 8/11 of the flag
<h3>Area</h3>
The area of a shape is the amount of space it occupies
The width is given as:
<h3>
Blue region </h3>
The blue region of the American flag has a dimension of 8 by 11 stars.
So, we have:
Where x represents the length of the blue region.
Express the ratio as fractions
Multiply both sides by 2/5
Rewrite as:
The area is then calculated as:
Simplify
Hence, the area of the blue rectangle is 8/11 of the flag
