What is the area of a sector with a central angle of 4π5 radians and a radius of 11 cm? use 3.14 for π and round your final answer to the nearest hundredth. enter your answer as a decimal in the box. cm²

Answer

Area of sector (A) is given by:

where,

r is the radius and is the angle in degree.

As per the statement:

A central angle of radians and a radius of 11 cm.

⇒r = 11 cm

Use conversion:

1  radian =

then;

radians =

⇒ degree

Substitute these given values and use 3.14 for π we have;

square cm.

Therefore, the area of a sector is, 151.976 square cm

(n^3 - n)

= n(n-1)(n+1)

since it is divisible by 3 and 2 ,because it is a multiple 3 consecutive number

if, n-1 is odd then n+1 is also odd, then it is a multiple of 9

but if, n-1 is even then n+1 is also even, then it is a multiple of 4

so, largest multiple = max(9*2, 4*3) = max(18, 12) = 18

your answer is 228

step-by-step explanation:

add the top and bottom bases together, then divide them by 2, then multiply by the height.
