Find the area of circle o if DCBO is a rectangle and DB measure 10 units

Dmitrij [34]

Answer:

$100\pi$

Step-by-step explanation:

Step 1: Identity the radius.

Since O is the center of the circle, and C and E lie on the circumference, OC and OE are the radii of the circle and thus,

OC=OE.

Step 2: Consider the rectangle.

All diagonals in a rectangle are congruent so this means

DB= OC ( OC is also a diagonal).

Thus, OC= 10 units.

Step 3: Analyze

So this means OE is also 10 units as well.

Since we know the length of the radius, Use the area of circle,

$\pi {r}^{2}$

$\pi( {10}^{2} ) = 100\pi$

So the area of a circle is 100 pi.

Salsk061 [2.6K]

Answer:

The height of the tree is 21 ft

Step-by-step explanation:

we know that

A light post that is 9 feet tall that casts a shadow that is 6 feet long

by proportion

Find out the the height of the tree if a tree that casts a shadow that is 14 feet long

Let

x ----> the height of the tree

$\frac{9}{6}=\frac{x}{14}\\\\x=9*14/6\\\\x=21\ ft$

therefore

The height of the tree is 21 ft

Mr. Johnson needs to buy seed for his backyard lawn.

Romashka [77]

Answer:

a. He will need $2,075.7\ ft^2$ of seed to cover the entire area.

b. He will need 5 bags of seed if he uses the highest setting and 7 bags of seed if he uses the lowest setting.

Step-by-step explanation:

a. You can calculate the area of his lawn by multiplying its dimensions.

The dimensions are:

$40\frac{4}{5}\ ft$ by $50\frac{7}{8}\ ft$

We can convert the mixed numbers to decimal numbers. To do this,we must divide the numerator by the denominator of the fraction and then we must add the quotient to the whole number part.

Then, these are:

$(40+0.8)\ ft=40.8\ ft$

$(50+0.875)\ ft=50.875\ ft$

Then:

$Area=40.8\ ft*50.875\ ft\\\\Area=2,075.7\ ft^2$

He will need $2,075.7\ ft^2$ of seed to cover the entire area.

b. Let be "h" the number of bags of seed that he will need if he uses the highest setting.

You know that one bag of seed will cover 500 square feet if he uses the highest setting. Then:

$h=\frac{2,075.7\ ft^2}{500\ ft^2}\\\\h=4.15\\\\h\approx5$

Let be "l" the number of bags of seed that he will need if he uses the lowest setting.

You know that one bag of seed will cover 300 square feet if he uses the lowest setting. Then:

$l=\frac{2,075.7\ ft^2}{300\ ft^2}\\\\l=6.9\\\\l\approx7$
