Tree casts a shadow 30 feet long. A MHS student standing near the tree casts a shadow 9 feet long. The  student is 6 feet tall. What is the height of the tree? Show all work

<em><u>Answer:</u></em>

Option D

The height of tree is 20 feet tall

<em><u>Solution:</u></em>

From given question,

Shadow of tree = 30 feet

Height of tree = ?

Height of student = 6 feet

Shadow of student = 9 feet

We have to find the height of tree

We can solve the sum by proportion

\frac{\text{height of tree}}{\text{shadow of tree}} = \frac{\text{height of student}}{\text{shadow of tree}}

This forms a proportion and we can solve the sum by cross multiplying

\frac{\text{height of tree}}{30} = \frac{6}{9}\\\\\text{height of tree} = 30 \times \frac{6}{9} = 30 \times \frac{2}{3}\\\\\text{ height of tree } = 10 \times 2 = 20

Thus height of tree is 20 feet tall

zalisa [80]

Answer:

The radius of the circle is 9 in

Choice C is correct

Step-by-step explanation:

254.4696 square inches. Whats the radius of the circle (use pie=3.1416.

The area of a circle with radius r is given as;

A=\pi *r^{2}

We substitute the given area and the value of pi given to solve for the radius;

254.4696=3.1416*r^{2}\\\\r^{2}=\frac{254.4696}{3.1416}\\\\r^{2}=81\\\\r=\sqrt{81}=9\\\\r=9
