Answer:
- Area of the circle is 113.04 ft²
Step-by-step explanation:
Given:
- Diameter of circle = 12 feet
To Find:
Using formula:
<em>Where,</em>
- π = 3.14
- Diameter = 12 feet
- Radius = 12/2 = 6 feet
On substituting the required values, we get:
Hence,
- Area of the circle is<u> </u>113.04 ft²
Answer:
The volume of the cone is approximately 453.0 cm³
Step-by-step explanation:
The volume of a cone is one third that of a cylinder with the same height and radius. That gives us 1/3 πr²h, where r is radius and h is height.
However, we are not given the height of the cone, but the side length. We can work out the height using the Pythagorean theorem, as we have a right triangle with the height, base radius, and length. You may recall that the Pythagorean theorem states that the square of the hypotenuse of a right triangle is equal to the sum of the squares of it's other two sides:
So we can find the height of the cone with that:
Now that we have the cone's height, we can solve for its volume:
