Answer:
119.64m^3
Step-by-step explanation:
Given that
The height is 12.7 m
And the base with the circumference is 18.9 m
We need to find out the volume of the right circular cone
As for determining it first compute the radius
As we know that
Circumference = 2πr
18.9 = 2 × 3.14 × r
r = 3m
Now the volume is
= 1 ÷ 3πr^2h
= 1 ÷ 3 × 3.14 × 3^2 × 12.7
= 119.64m^3
This equals to 2/(1/5)+(1/5)/2.
=2 x 5+1/5 x 1/2
=10+1/10
=10 1/10 <---- This is mixed fraction, since you didn't want decimals.
Answer:
Step-by-step explanation:
hello :
5x=(2x-2)(m+6) equivalent : 5x = 2xm+12x-2m-12
5x-2xm -12x=-2m-12
x(5-2m-12) = -2m-12
x(-7-2m) = -2m-12
x(2m+7) = 2m+12
if : 2m+7 ≠ 0 means m ≠ -7/2 so : x= (2m+12)/(2m+7)
if : 2m+7 = 0 means : m = -7/2 you have : x(0) = 2(-7/2)+12
0= 5 ( false) ... x no exist
50 / 100 = .5
.5 is 1% of 50
.5 * 20 = 10
Does that help?
