Answer: 7.9 cm

Step-by-step explanation:

Given : This figure is 1/4 of a circle.

The radius of the figure = 5 inch

We know that the perimeter of the circle is given by :-

perimeter =2\pi r

Then the perimeter of 1/4 of the circle is given by :-

perimeter =\frac{1}{4}\times2\pi r

\\\Rightarrow\ perimeter =\frac{1}{4}\times2(3.14)\times5.........[since\ \pi=3.14]\\\\\Rightarrow\perimeter=7.85\approx7.9\ cm

Hence, the perimeter of the given figure = 7.9 cm

Suppose a figure is located in Quadrant I. Which of the following sequences will result in an image that is located in Quadrant
vladimir2022 [97]
The answer that results in an image located in Quadrant II is <span>C. rotate 90 degrees counterclockwise, then shift 1 unit up. This is because Quadrant II is located next (at the left) of Quadrant I. This means that a 90 degree rotation and a shift up are safe enough to estimate it to land on Quadrant II.</span>
