Answer:
9.4 cm^3
Step-by-step explanation:
This figure is a cylinder so the formula is V=πr^2h
r is the radius and h is the height
Here we can see the height is 3 and the radius is 1
V=π(1)^2(3)
V=π3
V=9.42 (assuming π is 3.14)
Rounded to the nearest tenth is 9.4
Answer:
x=180
Step-by-step explanation:
6/30 = x/900
Answer:
15.7 cm
Step-by-step explanation:
Circumference= Diameter * Pi
Hence,
Circumference of the circle= 3.14 * 5
=15.7 cm
The inequality of the given question is x+2y ≥ 150
Step-by-step explanation:
Given,
The mark out of 100 for Term 1 exam and twice the mark out of 100 for the term 3 exam are added together.
And, he needs to obtain 150 to achieve the grade.
To find, the inequality to student mark
Let,
The student got x in Term 1 and y in Term 2.
To be passed, he needs to get x+2y
So, the requited inequality will be x+2y ≥ 150
The dimension of the parallelogram is length = 25 m and width = 15 m.
What is a parallelogram?
A quadrilateral with two sets of parallel sides is referred to as a parallelogram. In a parallelogram, the opposing sides are of equal length, and the opposing angles are of equal size. Additionally, the interior angles that are additional to the transversal on the same side. 360 degrees is the sum of all interior angles.
The perimeter of a parallelogram is 2(length + breath).
Let the breath of the parallelogram be x.
Given that the length of the parallelogram is 10 m longer than width.
The length of the parallelogram is (x + 10)m
The perimeter of the parallelogram is 2(x+10 +x) = 2( 2x + 10)
According to the question,
2(2x + 10) =80
Divide both sides by 2
2x + 10 = 40
Subtract 10 from both sides:
2x = 30
Divide both sides by 2
x = 15
The length of the parallelogram is (10 + 15) m = 25m.
