Answer:
A = 31.4 inches^2 to the nearest tenth of a square inch
Step-by-step explanation:
In this question, we are asked to calculate the area of the sector of a circle given the value of the radius and the angle subtended at the centre.
To calculate this, we employ a mathematical approach.
The area of the sector of a circle can be calculated as follows
A = ϴ/360 * π * r^2
Where ϴ is the angle subtended which is 100 and r is the radius.
Thus, we have
A = 100/360 * 22/7 * 6 * 6
A = 31.428 inches^2
To the nearest tenth of a square inch, A = 31.4 inches^2
Answer:
3p+2p+8-3=15
5p+5-15=0
5p-10=0
5(p-2)=0
(if you want to solve it p=2)
Answer:
c.) The absolute change is 35 students and the relative change indicates an increase of 23.3%
Step-by-step explanation:
the participants increasing = 185-150=35
the percentage = 35/150 × 100% = 23.3%
Answer:
see the explanation
Step-by-step explanation:
The picture of the question in the attached figure
we know that
The volume of a cube is equal to
where
b is the length side of the cube
In this problem we ha a cubes with a length side equal to 1 cm
so
substitute
The volume of each cube is equal to one cubic centimeter
so
To find out the volume of the figure, multiply the number of cubes by 1 cm^3
Looking at the figure
The total number of cubes is 6
therefore
The total volume is
Joyce's mistake was counting 5 cubes instead of 6 (there is one cube that is not in sight)
I think the 40 30 20 should be going up not down like this 20 30 40
