Answer:
314.2 cm^2
Step-by-step explanation:
The formula for the area of a circle of radius r is A = 3.14r^2.
With r = 10 cm, r^2 = 100 cm^2, and so the area of this circle is 314.2 cm^2, to the nearest tenth.
Answer:
3/4
Step-by-step explanation:
The answer is 3/4, because we rise 3 and run 4 the formula is always rise over run, and thats why its 3/4
Hoped this helped!!
When at least one of the factors still has a common factor
Answer:
see explanation
Step-by-step explanation:
For the triangles to be congruent.
The hypotenuse and a leg of the triangle on the left and the hypotenuse and a leg of the triangle on the right must be congruent, thus
4y = x + 4 → (1)
x = y + 8 → (2)
Substitute x = y + 8 into (1)
4y = y + 8 + 4 = y + 12 ( subtract y from both sides )
3y = 12 ( divide both sides by 3 ) )
y = 4
Substitute y = 4 into (2)
x = 4 + 8 = 12
Thus
x = 12 and y = 4
