Answer:
i think the answer is (12*3.14 = 37.68cm is the circumference and 6^2*3.14 = 113.04cm2 is the area.)
Step-by-step explanation:
For this case, the first thing we must do is define a variable.
We have then:
x: unknown number
We now write the expression that models the problem:

From here, we clear the value of x.
We have then:




Answer:
4/9 divided by 1/27 equals 12
Answer:

Step-by-step explanation:
Given the surface dimensions of the garden as 24 inches by 48 inches:
#Calculate surface area of the garden's top:

Given the soil's thickness is 2 Inches, we multiply this thickness by the garden's surface area to get volume of soil used:

Hence, the amount of soil used is 2304 cubic inches.
Answer:
Step-by-step explanation:
in a right angled triangle angles given are 45,90
Then third angle is also 45 °
as two angles are 45° each.
Then sides are also equal.
Let the equal sides be each =x
then hypotenuse=√(x²+x²)=√(2x²)=x√2
sin 45°=x/(x√2)=1/√2
Answer:
the answer is triangle GBL
