What would be the area of a regular polygon with a perimeter of 30 feet and an apothem of 4 feet?

1 answer:

8 0

60ft
Because the formula for a regular polygon is A=1/2(apothem)(perimeter). So first you would do is 1/2 times 4 which equals 4/2. 4/2 times 30 is 60, so 60 is the area.

The circumference of a circle can be found using the formula C = 2r. Which is an equivalent equation solved for r? r = C r = C(2

vaieri [72.5K]

Answer:

r equals StartFraction C Over 2 pi EndFraction

Step-by-step explanation:

we know that

The circumference of a circle is equal to

$C=2\pi r$

where

r is the radius of the circle

Solve for r

That means -----> isolate the variable r

Divide by 2π both sides

$\frac{C}{2\pi}=\frac{2\pi r}{2\pi}$

Simplify right side

$\frac{C}{2\pi}=r$

Rewrite

$r=\frac{C}{2\pi}$

r equals StartFraction C Over 2 pi EndFraction

telo118 [61]

Answer:

(a) $Unit = \frac{1}{4}/8$

Step-by-step explanation:

Given

$Time = \frac{1}{4}$

$Lap = 8$

Required

Determine the time in each lap

The unit time in each lap is calculated by dividing the total time by the number of laps; i.e.;

$Unit = \frac{Time}{Lap}$

Substitute values for Time and Lap

$Unit = \frac{1}{4}/8$
