We know that
with
scale factor 1=1 in/4 m
<span>the longer side of the ballroom-------> 44 m
scale factor= measure model/measure actual
measure model=scale factor*measure actual
</span>measure model=(1/4)*44------> 11 in
with
scale factor 2=1 in/7 m
measure actual=measure model/scale factor
measure actual=11/(1/7)-----> 77 m
the answer is
77 m
Note: The volume of a cylinder is:
radius² × π × height
First lets work out the volume of Cylinder A:
Volume = 1² × π × 4
= 4π m³
Now lets work out the volume of Cylinder B
Volume = 2² × π × 4
= 16π m³
__________________________________________
Now lets compare the volumes ( Cylinder A : Cylinder B) :
4π : 16π
Lets simplify this by dividing both sides by 4π:
4π : 16π <em>( </em>÷ <em>4π)</em>
----> 1 : 4

Answer:
Option b) 1 : 4
Answer:
real and rational
Step-by-step explanation:
If you look at the picture below, you'll see that -5/8, which is a negative fraction, falls into these two categories.
Answer:
C = 7pi yds
If we approximate pi by 3.14
C =21.98 yds
If we approximate pi by the pi button
C =21.99114858 yds
Step-by-step explanation:
The circumference is given by
C = 2*pi*r
C = 2 * pi * 3.5
C = 7pi yds
If we approximate pi by 3.14
C =21.98 yds
If we approximate pi by the pi button
C =21.99114858 yds
