Probably a circle. Its the same thing as cutting a cube and getting a square, and cross sectioning a pentagonal prism and getting a pentagon.

The perimeter of the rectangle is 2,500 cm. Find the unknown side length. the other side is 750

sineoko [7]

Answer:

Step-by-step explanation:

Perimeter of a rectangle = 2l + 2w

where

l is the length

w is the width

From the question we have

$2500 = 2l + 2(750) \\ 2500 = 2l + 1500 \\ 2l = 2500 - 1500 \\ 2l = 1000 \\ \frac{2l}{2} = \frac{1000}{2} \\ l = \frac{1000}{2} \\ l = 500$

We have the final answer as

Hope this helps you

A circle with radius of 4cm sits inside a circle with radius of 11cm.

sweet-ann [11.9K]

Answer:

Area of shaded region = 329.70 cm²

Step-by-step explanation:

Area of a circle = πr²

Area of bigger circle = 3.14 × 11²

= 3.14 × 11 × 11

= 379.94 cm²

Area of smaller circle = 3.14 * 4²

= 3.14 × 4 × 4

= 50.24 cm²

Area of shaded region

= Area of bigger circle - Area of smaller circle

= (379.94 - 50.24) cm²

= 329.70 cm²

Find cot theta if csc theta= the square root of 5/2 and tan theta>0

Nostrana [21]

Since $\cot^2\theta+1=\csc^2\theta$ , you have

$\cot^2\theta=\left(\dfrac{\sqrt5}2\right)^2-1=\dfrac14$
$\cot\theta=\pm\sqrt{\dfrac14}=\pm\dfrac12$

Since $\tan\theta>0$ , and $\cot\theta=\dfrac1{\tan\theta}$ , you know that $\cot\theta$ is also positive, which means

$\cot\theta=\dfrac12$
