Answer:
B. 2.2π m² : 3.2π m²
Step-by-step explanation:
Given:
Slant height (l) = 2.2 m
Diameter (d) = 2 m
Radius (r) = ½(2) = 1 m
Required:
Lateral area and surface area
Solution:
✔️Formula for lateral area of a cone = πrl
Plug in the values
Lateral area of the cone = π*1*2.2
Lateral area = 2.2π m²
✔️ Formula for surface area of a cone = πr(l + r)
Plug in the values
Surface area of the cone = π*1(2.2 + 1)
Surface area = π(3.2)
Surface area = 3.2π m²
The answer would therefore be:
2.2π m² : 3.2π m²
Answer:
575x.25=143.75 575-143.75=$431.25
21.95x.15=$3.29 tip total bill $25.24
Step-by-step explanation:
Since we have to solve the given formula for h(height) so, the correct option is (a)
5x = 4y - 3
The correct answer is D. 5x - 4y = -3
This is because standard form is the form ax + by = c, where a, b, and c are coefficients or constants of the variables x and y. Thus, Answer D (above) is the correct answer to this problem, as it is the only option that fits this.
Answer:
A
Step-by-step explanation:
we just substitute the value of "a" given in the above expression we get
21-2(3)
21-6=15
