Answer:
20π or 62.8
Step-by-step explanation:
Volume of a cone = 1/3πr²h
1/3(π)(2)²9
= 12π or 37.7
Volume of a hemisphere = 2πr²/3
2(π)(2)²
= 8π or 25.1
Total Volume = 20π or 62.8
I think and hope it is $ 267 because a dozen is 12
Answer:
25 students.
Step-by-step explanation:
A line plot is a simple graph that shows relationship among the values in a data using a number line.
From the line plot, each dot represents a student. While the number on the line shows the number of blocks walk each day by each student.
It can be deduced from the line plot that;
Only 1 student walks through 7 blocks, 2 walk through 5 blocks, 8 walk 4 blocks, 5 walk 3 blocks, 5 walk 2 blocks and 4 walk through 1 block to school each day.
So that;
1 + 2 + 8 + 5 + 5 + 4 = 25
Therefore, the number of students who took part in the survey is 25.
Answer:
b =15
Step-by-step explanation:
We can use Pythagoras theorem to find b:
64 + 
= 289
64 + 225 = 289
64 + 
= 289
b = 15
hope this helps :) and sorry if not right
