Answer:
(301)^2-(300)^2
it is in the form of
a^2-b^2=(a+b)(a-b)
so,
(301+300)(301-300)
(601)(1)=601

Answer:
The area of the sector is 3pi/2
Step-by-step explanation:
A sector is that part of a circle bounded by 2 radii and an arc
The circle has an area of 9 pi with a central angle of 60 degrees.
Now the area of the sector is pretty much straight forward to calculate. Since it is a circle, the total angle we have is 360.
Now the sector subtends an angle of 60 degrees at the centre. What this means is that the sector is exactly 1/6 of the circle. meaning that cutting the circle into 6 slices will give the sector.
Thus, the area of the sector is one-sixth the area of the circle.
The area of the sector is thus 1/6 * 9pi = 9pi/6 = 3pi/2 or 3/2 pi
Answer:
<h2>1 t-shirt cost $5</h2><h2>hat costs $2</h2>
Step-by-step explanation:
8 t-shirts and a hat cost £42.00
3 t-shirts and a hat cost £17.00.
<u>difference</u>
5 t-shirts cost $25
1 t-shirt cost $5
3 t-shirts cost $15
3 t-shirts and a hat cost £17.00.
<u>difference</u>
hat costs $2
The answer is 81 the right Column is multiplying by 3
