Use 3.14 for PI( π ) Diameter: 5 ft Formula: A= πr2

Liula [17]

Answer:

$\boxed {\boxed {\sf 19.625 \ ft^2}}$

Step-by-step explanation:

The area of a circle is found using this formula:

$a= \pi r^2$

We know the circle's diameter is 5 feet, but we don't know the radius. Remember the diameter passes through the center from one side to the other, while the radius connects the center and the side. Therefore, the radius is half the diameter.

r=d/2
r= 5 ft/2
r= 2.5 ft

We know the radius is 2.5 feet and we are using 3.14 for pi. Substitute the values into the formula.

$a= (3.14)* (2.5 \ ft)^2$

Solve the exponent.

(2.5 ft)²= 2.5 ft *2.5 ft=6.25 ft²

$a= (3.14)*(6.25 \ ft^2)$

Multiply.

$a=19.625 \ ft^2$

The area of the circle is 19.625 square feet.

Given: m∠LON=77 ° m∠LOM=9x+44 ° m∠MON=6x+3 ° Find ∠MON

NISA [10]

Answer:

$m\angle MON=15^o$

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

$m\angle LON=m\angle LOM+m\angle MON$ ---> by addition angle postulate

substitute the given values

$77^o=(9x+44)^o+(6x+3)^o$

solve for x

$77=(15x+47)$

$15x=77-47$

$15x=30\\x=2$

Find the measure of angle MON

$m\angle MON=(6x+3)^o$

substitute the value of x

$m\angle MON=(6(2)+3)=15^o$
