Answer:
1944 inche^2
Step-by-step explanation:
18*18 = 324 each face
324*6 = 1944
Answer:
The current area of the circle is 81π in².
They want to " 'decrease' " the radius to 9 in.
First, find the current radius for the current circle.
Areas of circle = πr²,
81π = πr²
First, divide π from both sides of the equation:
(81π)/π = (πr²)/π
r² = 81
Isolate the variable, r. Root both sides of the equation:
√(r²) = √(81)
r = √( 9 * 9) = 9
The radius currently is 9 in.
The NBA is not making any changes at all, therefore the question will be void. (Note that the other answer choice is -9, however, you cannot have a negative measurement, therefore, the answer is voided).

Answer:
The surface area of the triangular prism is approximately 401.582 square feet.
Step-by-step explanation:
The figure represents a triangular prism, the procedure for calculating the surface area of the entire figure consists in adding the areas of each face (3 rectangles and 2 triangles):
![A = 2\cdot \left[\frac{1}{2}\cdot (9\,ft)\cdot (4\,ft)\right] + (16\,ft)\cdot (4\,ft) + (9\,ft)\cdot (16\,ft) + (16\,ft)\cdot \sqrt{(9\,ft)^{2}+(4\,ft)^{2}}](https://tex.z-dn.net/?f=A%20%3D%202%5Ccdot%20%5Cleft%5B%5Cfrac%7B1%7D%7B2%7D%5Ccdot%20%289%5C%2Cft%29%5Ccdot%20%284%5C%2Cft%29%5Cright%5D%20%2B%20%2816%5C%2Cft%29%5Ccdot%20%284%5C%2Cft%29%20%2B%20%289%5C%2Cft%29%5Ccdot%20%2816%5C%2Cft%29%20%2B%20%2816%5C%2Cft%29%5Ccdot%20%5Csqrt%7B%289%5C%2Cft%29%5E%7B2%7D%2B%284%5C%2Cft%29%5E%7B2%7D%7D)
The surface area of the triangular prism is approximately 401.582 square feet.
Of pie right <span>The square root of pi, like pi itself,
is an irrational number. It can be approximated to four decimal places
by 1.7725. The factorial of 1/2 is equal to half of the square root of pi.</span>
