Answer:
1.646×10¹¹ km³.
Step-by-step explanation:
From the question given, we obtained the following information:
Radius (r) = 3400 km
Volume (V) =.?
The shape of a planet is spherical in nature. Thus, we shall apply the formula for calculating the volume of a sphere to obtain the volume of Planet Mar as illustrated below:
Radius (r) = 3400 km
Pi (π) = 3.14
Volume (V) =.?
Volume of a sphere = 4/3 πr³
V = 4/3 × 3.14 × (3400)³
V = 4/3 × 3.14 × 3.9304×10¹⁰
V = 1.646×10¹¹ km³
From the calculations made above, the volume of Planet Mar is 1.646×10¹¹ km³
Answer:
Step-by-step explanation:
The angles of a quadrilateral have to add up to equal 360. That means that
1x + 2x + 3x + 4x = 360 and
10x = 360 so
x = 36. Then
2x = 72 and
3x = 108 and
4x = 144
Angle A and angle D are opposite angles, as are angles B and C. This is because opposite angles are supplementary.
Answer:
(-5, 3)
Step-by-step explanation:
Let O(x, y) be the centroid of the triangle.
The median of a triangle is a line segment that joins the vertex of a triangle to the midpoint of the opposite side. There are three medians in a triangle; and the medians of a triangle intersect at a point called the centroid.
The centroid of a triangle is gotten from the average of the x coordinates and the y coordinates of all the three vertices.
For Triangle ABC has vertices A (3,-3) B (-7,9) C (-11,3) and centroid O(x, y). Hence:
The centroid is at (-5, 3)

Answer:
x = 11
Step-by-step explanation:
The external angle is half the difference of the subtended arcs. The smaller arc is shown as 86°. The larger arc will be the difference between 360° and the two arcs shown.
larger arc = 360° -74° -86° = 200°
So, the external angle is ...
4x +13 = (200 -86)/2 = 57
4x = 44 . . . . . . . . . . . . subtract 13 from both sides
x = 11 . . . . . . . divide by 4
Answer:
Step-by-step explanation:
you put the -9 above where it says the -9 and same to the -3
or to solve the equation:
Divide both sides of the equation by the same term
−9=−3−9−3=−3−3
Divide the numbers
−9−3=−3−3
3=−3−3
Cancel terms that are in both the numerator and denominator
Move the variable to the left =3x=3
Solution =3
