If the area of a circle is 58 square feet, find the circumference. A. 42.5 ft. B. 4.25 ft. C. 22.35 ft. D. 26.99 ft.

PSYCHO15rus [73]

Answer: OPTION D.

Step-by-step explanation:

The formula for calculate the circumference of a circle is:

$C=2r\pi$

Where <em>r</em> is the radius.

The formula for calculate the area of a circle is:

$A=r^2\pi$

Where <em>r</em> is the radius.

Solve for <em>r</em> from $A=r^2\pi$ to calculate it:

$r=\sqrt{\frac{A}{\pi}}\\r=\sqrt{\frac{58ft^2}{\pi}}\\r=4.296ft$

Subsitute the radius into $C=2r\pi$ . Then:

$C=(2)(4.296ft)\pi=26.99ft$

Find the fifth term in the geometric

OlgaM077 [116]

Answer:

Step-by-step explanation:

The nth term in the geometric sequence: $a_n=a_1\cdt r^{n-1}$

a₁ = 2 and r = 3

So:

$a_5=a_1\cdot r^4=2\cdot3^4 = 2\cdot81=162$
