There are 300 student and teachers at a sports event.Grade k to 2 is students: 137 Grade 3 to 5 students: 145 Teachers: ? what is the percentage of teachers at the sports event.

6%

Percentage of teachers = 6%

Step-by-step explanation:

Given;

Number of grade k-2 students = 137

Number of grade 3-5 students = 145

Total = 300

Number of teachers = 300 - (137+145) = 18

Percentage of teachers = (number of teachers÷total)× 100%

%T = (18/300) × 100

%T = 6%

Approximate radius of cone's base is 21 units

Approximate volume of the cone is 9702 cubic units

Step-by-step explanation:

1. Area of the base (which is a circle) is given as 1386. We know that area of a circle is given as

Equating this to 1386 and solving for :

is approximately 21 units

2. Volume of Cone is given by

Given radius and height are equal and they are 21 units each, plugging in the values we get:

Volume of Cone =

Volume of Cone is approximately 9702 cubic units.
