Answer:
The cup can hold 235.5 cubic cm of popcorn.
Step-by-step explanation:
A cone shaped popcorn cup has a radius of 5 cm and a height of 9 cm.
Use 3.14 as an approximation for pi.
Now, to find cubic cm of popcorn the cup can hold.
Radius (r)= 5 cm
Height (h)= 9 cm
= 3.14 (as per question).
So, to get the cubic cm of popcorn the cup can hold we put formula of volume:
Volume= r h 3
Volume= 3.14 x 5 × 93
Volume= 3x14 x 25 x 3
Volume= 235.5 cubic cm.
Answer:
2.33
Step-by-step explanation:
We shall use the z distribution because we know the population standard deviation.
The margin of error formula is given by:
The z-value for 98% confidence interval is 2.326.
The sample size is n=25.
The population standard deviation is is
We substitute the values into the formula to get:
Evaluate square root:
