If I did my math right, the right answer should be that the surface area of this triangular prism is 576 square meters.
Answer:
Step-by-step explanation:
Area of a circle is defined as
A = πr²
Where
A is the area of the circle
r Is the radius of the circle
π is a constant = 3.142
Then,
Given that the area is 380 in²
So,
A = πr²
380 = 3.142 × r²
Divide both side by 3.142
380 / 3.142 = 3.142 × r² / 3.142
111.372 = r²
Take square root of both sides
√111.372 = √r²
10.5533 = r
r = 10.5533 in
Nearest hundredth means to 2d.p
Therefore
r = 10.55 inches
Answer:
7/2 but as a mixed number 3 1/2
Step-by-step explanation:
Unit rate would be 50 because 250÷5=50, so the answer would be (250×3)+50, witch is 800.
