Answer:

\boxed {\boxed {\sf a \approx 113.0 \ ft^2}}

Step-by-step explanation:

The area of a circle is the space inside the shape. The formula is:

a= \pi r^2

We know the radius of the circle is 6 feet and we are using 3.14 for pi.

  • r= 6 ft
  • π= 3.14

Substitute the values into the formula.

a= (3.14) \times (6 \ ft)^2

Solve the exponent.

  • (6 ft)² = 6 ft * 6 ft = 36 ft²

a= (3.14) \times 36 \ ft^2

Multiply.

a=113.04 \ ft^2

Let's round to the nearest tenth. The 4 in the hundredth place tells us to leave the 0 in the tenths place.

a \approx 113.0 \ ft^2

The area of the circle is approximately <u>113.0 square feet.</u>

Secant jkl and jmn are drawn to circle o from an external point ,j. if jk=8,lk=4 and jm=6 what is the length of jn answer
Archy [21]
See the picture attached to better understand the problem

we know that
If two secant segments are drawn to a <span>circle </span><span>from an exterior point, then the product of the measures of one secant segment and its external secant segment is equal to the product of the measures of the other secant segment and its external secant segment.
</span>so
jl*jk=jn*jm------> jn=jl*jk/jm

we have
<span>jk=8,lk=4 and jm=6
</span>jl=8+4----> 12

jn=jl*jk/jm-----> jn=12*8/6----> jn=16

the answer is
jn=16

WHOEVER ANSWERS FIRST GETS BRAINLIEST!!!!
Ratling [72]

Answer:

A, C and E are true.

Step-by-step explanation:

The domain is a set of natural numbers.

The recursive formula is correct:

When x = 1, f(x) = 4 and f(x + 1) = f(2) = 3/2 f(x) = 3/2 * 4 = 6.

It is also true for the other points on the graph.

D is  incorrect.

E is correct exponential growth with the formula  4(3/2)^(x-1).
