Answer:
33/100
Step-by-step explanation:
Answer:
242.76m^2
Step-by-step explanation:
Given data
Height=18m
Volume=4,374m^3
We know that the expression for the volume of a cylinder is
V=πr^2h
substitute
4374=3.142*r^2*18
4374=56.556*r^2
4374/56.556=r^2
77.339=r^2
r=√77.339
r= 8.79m
But the area of a circle is expressed as
A= πr^2
A=3.142*8.79^2
A=3.142*77.2641
A=242.76m^2
Hence the area of the base is 242.76m^2
Answer:
61
Step-by-step explanation:
Given the exponential expression, (2・3)² + 5²:
Start by multiplying 2 and 3 inside the parenthesis, before performing other mathematical operations.
(2・3)² + 5² = (6)² + 5²
Next, perform the exponential operations for (6)² and 5², then add their squared values together:
= 36 + 25 = 61
Answer:
Step-by-step explanation:
we know that
Let
x-------> the number of nickels
y-------> the number of dimes
------> isolate the variable y
--------> equation A
------> multiply by 
both sides
-------> equation B
Substitute equation A in equation B and solve for x
