Quick i need help thank you, i wil give branliest

Step-by-step explanation:

The formula for the volume of a cone is:

First, we must find the radius. The diameter is 12 meters and the radius is half of the diameter.

r= d/2 r= 12 m /2 r= 6 m

The radius is 6 meters and the height is 5 meters.

Solve the exponent.

(6 m)²= 6 m * 6 m = 36 m²

Multiply the numbers in parentheses.

Multiply by 1/3 or divide by 3.

There are 3 ways to finish solving this.

1. In Terms of Pi

Leave the answer as it is, with pi included:

2. Using 3.14 as Pi

3. Using the Pi Button on a calculator

The volume of the cone is 60π, 188.4, or 188.495559 cubic meters.

Answer: d. 39 cmin the diagram, the approximate length of the minor arc de is 39 centimetres.step-by-step explanation: the formula for the length of an arc in a circle is as displayed below.let the length of the minor arc de = xx = 2( pi )r × angle of sector / 360°from this, we will substitute the values given from the problem into the formula to obtain the length of the minor arc de.x = 2( pi )r × angle of sector / 360°r = radius = 25cmpi as an approximate value = 3.14angle of sector = 120°x = 2( 3.14 )( 25 ) × 120° / 360°x = 157 × 1 / 4x = 39.25x = 39 ( rounded to the nearest whole number as an approximate value )
