Answer:
So we know the formula to calculate the area of the circular sector:
S=(r^2*π*a)/306°=
(5^2*3.14*40°)/360°= (1000*3.14) /360=8.72cm^2 so the right alternative should be the first one ,A.
Step-by-step explanation:
r - radius of the circle
a - corner of the circular sector
S - surface
Answer:That is incorrect. 12.8 is greater than 12.68 because .8 is greater than .68
Step-by-step explanation: Since “68” has been placed after the decimal, it is actually “.68” which is less than 1. From here, you have to figure out if .8 or .68 is closer to the number 1 and since .8 is closer, point 12.8 is greater than 12.68

Answer: Our required equation will be
Step-by-step explanation:
Since we have given that
Jack and Jill walked 4 yards every three seconds
As we know that
Now, we need to find the find the equation to represent the distance,<em>d</em>,
Jack and Jill walked over time <em>t </em>.
So here it is,
Hence, our required equation will be
Answer:
= 94
Step-by-step explanation:
To work out the multiplier, first add or subtract the percentage from 100, then convert to a decimal. Example: we want to add 20% to £110. To work out the multiplier, add 20 to 100, to get 120, and then change it to a decimal (divide by 100) to get 1.2. The answer is £110 x 1.2 = £132.
so to workout an increase of 9% followed by 3% we would do:
9% - 3% = 6%. convert = 0.06 = 100-6 = 94 converted into 0.94 x 100 = 94
