Sondra has a conical bird feeder with a circular top. the volume of the bird feeder is 153.86 cubic inches. the height of the feeder is 12 inches. what is radius of the top? use 3.14 for . round the answer to the nearest tenth. 3.5 in. 7.0 in. 12.3 in. 49.0 in.

3.5 inches

Step-by-step explanation:

Given: The volume of the conical bird feeder = 153.86 cubic inches

The height of the conical bird feeder = 12 inches

We know that the volume of a cone is given by :-

Hence, the radius of the top of the cone= 3.5 inches.

answer: add the !

step-by-step explanation: then we will answer

c.   x=2.4cm

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
