Step-by-step explanation:
Solution:
Here,
Volume of the tank=539 litres
=539×1000cm^3=539000cm^3
Height=1.4×100cm=140cm
Let the radius of the base be r cm
Then,
22/7×r^2×140=539000
or,r^2=539000×7/22×140
or,r^2=1225
or,r=35 cm
So,
Area of base=pie r^2
=22/7×35^2
=3850 cm^2

I can prove it without calculator so you believe me:
Answer:
the measure of the inscribed angle is equal to the measure of its intercepted arc.
Step-by-step explanation:
A quadratic graph will surely help you find the solutions
X2-x-2=0
x1=2 x2= -1
Substitute each of the x value in the original equation to get the y value
(2)^2-(2)-2= 0 (2,0)
(-1)^2-(-1)-2=-2 (-1,-2)
plot the coordinates on the graph,the graph should be a curve
Answer:
B) x+22
Step-by-step explanation:
PS= PQ+QR+RS
PS= 2x+4+8+10-x
PS= x+22
Hope this helps you.
