<u>Answer-</u>

<u>Solution-</u>
We know that arc length is the product of radius and central angle in radian.
i.e 
Here,

So,




You multiply the two together
x times x equals x squared ( x^2) the x times 2 which equals 2x, then multiply the 3 and x to get 3x and multiply 3 times 2 = 6
so now your problem looks like x[tex] x^{2} + 2x +3x +6 ( now combine like terms) which gives you x^{2} +5x +6, and thats the answer
Answer: 3.125
Step-by-step explanation:
Given
Triangle is dilated by a factor of
i.e. each side multiplies to 0.25.
Side E'F' becomes 0.25 times the original length

Answer:
Hi, there! The total surface area of that prism is 118 cm^2.
Step-by-step explanation:
The three rectangles on the side are called the lateral area, and they add up to 98(I'm assuming you know how to find the area of a 2d shape), and as for the triangles on the sides, you can just use the formula which is
.
Hope this helps :)
