Convert the angle 0 = 228° to radians.<br> Express your answer exactly.
Blizzard [7]

Answer:

\frac{19 \pi}{15}

Step-by-step explanation:

To convert a given angle from degrees to radians, we multiply by

\frac{ \pi}{180}

The given degree measure is 228°

Its radian equivalence is

\frac{ \pi}{180}  \times 228 =  \frac{19 \pi}{15}

Therefore the exact value of 228° is

\frac{19 \pi}{15}  \: radians

pickupchik [31]

Answer:

V = 24.28 in ^3

Step-by-step explanation:

The area of the base is

A =5/2 × s × a  where s is the side length and a is the apothem

A = 5/2 ( 2.13) * .87

A = 4.63275

The volume is

V = Bh  where B is the area of the base and h is the height

V = 4.63275 ( 5.24)

V =24.27561 in^3

Rounding to the  hundredth

V = 24.28 in ^3
