Answer:
The volume of solid is 268.08 inches cube.
Step-by-step explanation:
The solid spherical ball has height 8 inches that means the diameter of the sphere is 8 inches. So, the radius will be the half of diameter. Thus, radius is 4 inches.
Now use below formula to find the volume of solid sphere.
Therefore, the volume of solid is 268.08 inches cube.
Answer:
Area = 88 m²
Perimeter = 44 m
Step-by-step explanation:
✔️Area of the shape = area of the rectangle + area of the square
Area of the rectangle = L*W
L = 12 m
W = 6 m
Area of rectangle = 12*6 = 72 m²
Area of the square = s²
s = 4
Area of the square = 4² = 16 m²
Area of the shape = 72 + 16 = 88 m²
✔️Perimeter = sum of the sides surrounding the shape = 12 + 6 + 4 + 4 + 4 + 4 + 4 + 6 = 44 m
Answer:
2M will be:
Therefore, the 2nd option is true.
Step-by-step explanation:
Given the matrix
Multiplying by 2 will basically be a scalar multiplication.
Therefore, multiply each of the matrix elements by a scalar.
Hence, 2M will be:
Therefore, the 2nd option is true.
Answer:
△ VUW = △ KJI
Step-by-step explanation:
In △ VUW, △ KJI,
UW = JI ( Sides are equal )
∠ VUW = ∠ KJI ( From the diagram )
∠ UWV = ∠ KIJ ( From the diagram )
By ASA rule of congruency,
△ VUW is congruent to △ KJI.
