Multiply normally don't even look at the decimal point then look at how many numbers are after the decimal point after multiplying, then the many times the numbers are after the decimal point in both numbers you will place that decimal point that many places FROM the RIGHT.
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:
15
Step-by-step explanation:
3 and 5 are not common denominators so you have to find the lowest common denominator which is 15 because 3 times 5 is 15
