Answer:
b: irrational
Step-by-step explanation:
(√5+2)
-------------- is given.
(√5 - 2)
If we multiply numerator and denominator by (√5+2), we succeed in removing the square root symbol from the denominator:
(√5+2)(√5+2)
---------------------
(√5+2)(√5- 2)
and the denominator becomes 5 - 2, or 3. The denominator is now rational, but the numerator still involves the square root symbol, so overall the given number is irrational.

Find the volume of a cone with a radius of 6 centimeters and a height of 15 centimeters. Round your answer to the nearest tenth.
Answer: 565.3 cubic cm
Step-by-step explanation:
V= 1/3Bh
V= 1/3π r^2h
= 1/3 π (6 cm) ^2 (15 cm)
= 1/3 π (36 cm squared) (15 cm)
= 180π cubic cm
about 565.2 cubic cm
π is about 3.14
The value of the volume of a cone with a radius of 6 centimeters and a height of 15 centimeters is,
⇒ 565.2 cubic cm
What is Multiplication?To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Given that;
In cone,
Radius = 6 cm
Height = 15 cm
Now, We know that;
Volume of cone is,
V = 1/3π r²h
Substitute all the values we get;
V = 1/3 π (6 cm)² (15 cm)
V = 1/3 π (36) (15)
V = 180π
V = 565.2 cubic cm
Thus, The value of the volume of a cone with a radius of 6 centimeters and a height of 15 centimeters is,
⇒ 565.2 cubic cm
