Answer:
25 sq. units
Step-by-step explanation:
Because it is a square, you only have to find one if its side lengths. Let's say you choose to find the distance between B and C. You'll be finding the length of a hypotenuse due to the fact that the two points are diagonal from each other. Use the x and y values to discover the lengths of the legs of the triangle. In this instance, they are 3 and 4. Using background knowledge of the properties of triangles, I know that the hypotenuse of a right triangle with legs of 3 and 4 must be 5. Therefore, the side length of this square is 5. To find the area of a square, simply multiply its side length by itself. 5 x 5 = 25!
I think that the answer is the fourth one
Answer:
113.1
A = 2πrh + 2πr² = 2 × π × 3 × 3 + 2 × π × 3² ≈ 113.1
Answer:
20.35
Step-by-step explanation:
Calculator
8. 90° When a perpendicular line is drawn, the measure of both of the angles equal 90°.
9. Just draw two parallel lines, name them x and y. Then, draw a line through both of them and name it k.
10. Draw two parallel lines and draw a perpendicular line going through both r and s. All the angles will measure 90°.
11. Set it up like #9. and make the alternate interior angles congruent.
