An arc subtends a central and measuring pi/2 radians.

Sindrei [870]

Answer:

1/4th

Step-by-step explanation:

This comes from knowing the unit circle in both radians and degrees. However, you could also calculate it from knowing that 360 degrees is 2 $\pi$ radians. What you'll find is that $\frac{\pi }{2}$ radians is 90 degrees, or 1/4th of the circle. This means that an arc measuring $\frac{\pi }{2}$ radians will be 1/4th of the entire circumference.

I hope this helps!

I keep putting in the formula but I keep getting the answer wrong

Advocard [28]

Answer:

314 in² (nearest whole number)

Step-by-step explanation:

Radius of a regular polygon: The distance from the center of the polygon to any vertex. The radius of a hexagon is equal to the length of one side.

Therefore, from inspection of the given diagram:

radius = 11 in ⇒ side length = 11 in

To find the area of a regular polygon, we first need to calculate the apothem. The apothem is the line drawn from the center of the polygon to the midpoint of one of its sides.

$\textsf{Length of apothem (a)}=\dfrac{s}{2 \tan\left(\frac{180^{\circ}}{n}\right)}$

where:

s = length of one side
n = number of sides

Given:

s = 11 in
n = 6

Substitute the given values into the formula and solve for a:

$\implies \textsf{a}=\dfrac{11}{2 \tan\left(\frac{180^{\circ}}{6}\right)}=\dfrac{11\sqrt{3}}{2}$

Area of a Regular Polygon

$\textsf{A}=\dfrac{n\:s\:a}{2}$

where:

n = number of sides
s = length of one side
a = apothem

Given:

n = 6
s = 11

$\textsf{a}=\dfrac{11\sqrt{3}}{2}$

Substitute the given values into the formula and solve for A:

$\implies \sf A=\dfrac{6 \cdot 11 \cdot \dfrac{11\sqrt{3}}{2}}{2}$

$\implies \sf A=314.3672216...$

$\implies \sf A=314\:\:in^2\:\:(nearest\:whole\:number)$

1. Find the value of 8.3 x 24.2 x 0.03. Round your answer to the nearest hundredth.

MrMuchimi

The rounded value is option B) 6.03 which is rounded to the nearest hundredth.

Step-by-step explanation:

To find the value of 8.3 x 24.2 x 0.03, we need to multiply the given numbers to get a decimal value.
And then, after getting the value of 8.3 x 24.2 x 0.03 it should be rounded to the nearest hundredth.

So, let's multiply the numbers first :

8.3 × 24.2 × 0.03 = 6.0258

The value is 6.0258

To round the value 6.0258 to the nearest hundredth :

The first number next to the decimal point represents the tenth.
The second number next to the decimal point is the hundredth.
The third number next to the decimal point is thousandth.

Therefore, to round the value to the nearest hundredth, look for the thousandth number is either less than 5 or greater and or equal to 5.

If, thousandth place is greater or equal to 5, then the hundredth number should be increased by 1.

The hundredth is 6.02 and the number in the thousandth place is 5. So add 1 to the hundredth place.

The value is rounded to 6.03 to the nearest hundredth.
