Hey there! And welcome to Brainly.

Remember that the area of a circle is π*radius^2
Remember that there are 360° in a circle.

The angle of the unshaded part would be 360° minus the shaded part of 60°.
360°- 60° = 300°
Since the area of a circle is πr^2, and the section of the circle is 300°, or 300/360 = 5/6 or one full circle, the area of the unshaded region is
(5/6)π*radius^2
= (5/6)π*12^2
= 120π units^2

A cylinder has a height of 6 meters and a radius of 3 meters. What is its volume? Use ≈ 3.14 and round your answer to the near

bija089 [108]

Answer:

169.56 m³

Step-by-step explanation:

» Concepts

The volume of a cylinder is how much space there is inside the cylinder. The formula to find the volume is πr²h, where r = radius and h = height. Once you get the volume, you have to add <unit>³.

» Application

We are given the radius as three meters and the height as six meters; we also have to use π as 3.14. Now, we just have to plug in these values into the aforementioned formula.

» Solution

$3.14*3^3*6$
$3.14*9*6$
$28.26*6$
$169.56$

castortr0y [4]

To solve this problem you might have to use this formula y=a(1+r)^t A=amount of money you already have 1= a set number R= rate T= time YOUR GIVENS ARE: A=4000 R= 3.5% (0.035) decimals T= 3 years NOW lets plug IN everything in the FORMULA y=4000(1+.035)^3= $4434.87. NOW lets subtract 4000-4434=434. She earned $434 of simple interest.
