Step-by-step explanation:
here's your solution
=> volume of circular cone = (1/3)πr^2h
=> radius = 4 cm ,, height = 9 cm
=> volume of cone = (1/3)*(22/7)*16*9
=> volume of circular cone = 150.8 cm^3

Given:
The number is
.
To find:
The estimate value of given number.
Solution:
We have,

It can be written as

We know that,
. So,


Approx the value to the nearest integer.

Therefore, the required integer is 11.
Answer:
50°
Step-by-step explanation:
Let :
Let the angle = x
Second angle = x + 10
Third angle = x - 10
Sum of angles in a triangle = 180
x + (x + 10) + (x - 10) = 180
x + x + 10 + x - 10 = 180
3x = 180
x = 180 / 3
x = 60
Smallest angle :
x - 10 = 60 - 10 = 50°
Answer:
Zx = 24 degrees
Step-by-step explanation:
since it is supplementary it adds up to 180 degrees. so you have part of the angle (156 degrees) so the equation would be 180 - 156 = Zx (origionally Zx + 156 = 180).
Her rate of commission being 8% on an amount of $4,500, then her commission in $ will be :
8% x 4500 = 0.08 x 4500 = $360
So her commission = $360
