Answer:
1 and 3
Step-by-step explanation:
- The amount of rain in inches will be in numbers .So its random variable
- No of books purchased is also a numerical .So its a random variable.
Step-by-step explanation:
General formula for the area of a circle = πr^2.
Since the diameter is 8, the radius is 4 (half of diameter)
So the area is π(4)^2 = 16π.
Answer:
I think it is 4.5/6.5
Step-by-step explanation:
3 feet width is added to both sides .
so the dimensions become 34 feet and 36feet
hence the fencing length required or the perimeter= 2(l+b)
= 2( 34+36)
= 2(70)
= 140feet fence
Increase the height so that the slant height triples.
For example:
Say that lateral height is 2 and the radius is 1. The lateral surface area would be 6.28
if I make the lateral height 6, which is triple the original lateral height, the lateral surface area becomes 18.84, which is triple the original surface area
Hope I help :P
