Answer:
the area of a sector is 151.976 cm²....
Step-by-step explanation:
Area of sector(A)is given by:
A=πr².θ/360°
where,
r is the radius and θ is the angle in degree.
As per the statement:
A central angle of 4π/5 radians and a radius of 11 cm.
r=11cm
Use conversion:
1 radian=180/π
then:
4π/5 radians=180/π * 4π/5
=144°
θ=144°
Substitute these given values and use 3.14 for π we have;
A=3.14*(11)²*144/360
A=3.14(121)*144/360
A=379.94*0.4
A=151.976 cm²
Therefore the area of a sector is 151.976 cm²....

Answer:
The new granite countertop will cost $824.
Step-by-step explanation:
Step 1: The problem is to determine how many yards per square that the countertop is made up of.
This is the equivalent of finding the square area of the countertop.
The formula for the square area of a rectangle is given as L x W.
Where L = Lenght which is equal to 3 yards
W = 1 yard
Step 2:
Cost of per square yard required therefore is
3 x 1 = 3 square Yards.
The granite required for the countertop project therefore will cost:
$206 x 3 = $824.00
Cheers!
Answer: A) 184
Explanation:
Out of 17 bottles from the sample, 1 of them were defected, we are left with a fraction of 1/17 of cups out of the total would be defected. We multiply that fraction with the 3125 bottles that machine A produces to find how many defected bottles are produced by it a day.
(1/17) x 3125 = 183.8
The answer is 183.8, after rounding to the nearest one, the answer is 184.
The correct answer for this question is 68.
