15.7 m
314 m
Answer:
The answer is given in the picture
PLEASE MARK ME BRAINLIEST IF MY ANSWER IS CORRECTAnswer:
31.4 m
Step-by-step explanation:
The formula for the circumference of a circle is c=dπ, so we can substitute our diameter and 3.14 for pi.
c=(10)(3.14)
c=31.4
So the diameter is 31.4 meters.

The vertical of three squares are joined to form a right triangle , what is the area of the largest square
A- 25cm^2
B- 202,500cm^2
C- 34cm^2
D- 43cm^2
Answer:
43cm²
Step-by-step explanation:
let's first consider the area of a square.
the area is L² which means all sides are equal so we take the length times the breadth which is both equal because like we said all sides are equal.
so to find the side of the square using the area, we take the square root of both of the area.
[tex] \sqrt{25} = 5[/tex]
and also
[tex] \sqrt{18} = 4.2[/tex]
so we have the height of the triangle as 5cm and the base is 4.2cm.
now, from the triangle, since we have two sides and it's a right-angled, we can use Pythagoras' formula.
[tex] \sqrt{ {5}^{2} + {4.2}^{2} } = 6.53cm[/tex]
so the side 6.53cm is also the same side as the largest triangle. Since it's a square, all sides are equal. So we find the area of the largest triangle by using the formula
Area = L²
Area = 6.53²
Area = 42.6cm
the nearest cm square
Area = 43cm²

Say that romania puts a tariff of 6% on its exports and 21% on its imports. if romania has a trade deficit of (equivalent us dollars) $26.76 billion and gained tariff revenue of $18.9603 billion, how much are romania’s imports worth? a. $62.56 billion b. $64.29 billion c. $76.17 billion d. $97.04 billion please select the best answer from the choices provided a b c d
The amount of money that Romania’s imports are worth is equal to: C. $76.17 billion.
Given the following data:
Exports tariff = 6% = 0.06.
Imports tariff = 21% = 0.21.
Trade deficit = $26.76 billion.
Tariff revenue = $18.9603 billion.
How to calculate Romania’s imports?In order to determine how much Romania’s imports are worth, we would write a mathematical expression for the total tariff revenue and trade deficit as follows:
0.06E - 0.21I = 18.9603 .....total tariff revenue (eqn. 1).
I - E = 26.76 .....trade deficit (eqn. 2).
From eqn. 2, we have:
E = I - 26.76 ..equation 3.
Substituting eqn. 3 into eqn. 1, we have:
0.06(I - 26.76) - 0.21I = 18.9603
0.06I - 1.6056 - 0.21I = 18.9603
0.27I = 18.9603 + 1.6056
0.27I = 20.5659
I = 20.5659/0.27
I = $76.17 billion.
