The
lateral area of a cone is the surface area (aka area of the sides of the object) minus the area of the base of the cone.
The equation for the lateral area of a cone is:

where r = radius and l = slant height.
Since you know that the lateral area =

and the radius, r = 50 cm, you can plug those values into the equation for the lateral area and solve for l, the slant height:
The slant height of the cone is A) 10cm.
Answer:
Seven
Step-by-step explanation:
Let G7, G8, and G9 be the numbers of students in the respective grades.
Then, G7 + G8 + G9 = LCM of G8 and G9
<em>Data:
</em>
G8 = 5
G9 = 3
<em>Calculations:
</em>
<em>Multiples of 5</em>: 1 2 10 15
<em>Multiples of 3</em>: 1 3 6 9 15
The <em>LCM</em> of 5 and 3 is 15.
G7 + 5 + 3 = 15 Combine like terms
G7 + 8 = 15 Subtract 8 from each side
G7 = 7
There are seven students in Grade 7.
You would have to subtract both of them and you will get 9/10 stephens jump was further
Answer:
113
Step-by-step explanation:
290 - 64 = 226
226 ÷ 2 = 113
Answer:
13800
Step-by-step explanation:
The order of the members is important (because each selected member will receive a different position), thus we then need to use the definition of permutation.
There are 25 members, of which 3 are selected.

Evaluate the definition of a combination:
