Answer:
50.29 square inches.
Step-by-step explanation:
Given:
Sara is cutting circles out of pieces of cardboard.
She uses a rectangular piece of cardboard that is 8 inches by 10 inches.
Question asked:
What is the area of the largest circle she could make?
Solution:
Here given length of piece of cardboard is 10 inches and breadth is 8 inches, to draw the largest circle, we have to draw the circle touching the boundary of the breadth of the rectangular cardboard and hence breadth will be considered as diameter and it will be the maximum diameter of the circle.
Now, we will find the area of the largest circle by taking breadth as the maximum possible diameter:
Breadth = Diameter = 8 inches ( given )
Radius = half of diameter ,
Therefore, area of the largest circle she could make is 50.29 square inches.
Answer:

Step-by-step explanation:
Answer:
95 ft²
Step-by-step explanation:
Given:
regular pyramid with,
Square base of side length (s) = 5 ft
Slant height (l) = 7 ft
Required:
Surface area
Solution:
Surface area of a regular pyramid = ½*P*l + B
Where,
P = perimeter of the square base = 4(s) = 4(5) = 20 ft
l = slant height = 7 ft
B = area of base = s² = 5² = 25 ft²
Surface area = ½*20*7 + 25
= 10*7 + 25
= 70 + 25
Surface area of regular pyramid = 95 ft²
Answer:
C.
Step-by-step explanation:
It is the complement of the circle in the square
Okay,
Let the square be Universal set(U) and the circle be A
So
A complement = A' = U-A So
The shaded area is the complement of the circle
Answer:
C
Step-by-step explanation:
Mechanical weathering, also called physical weathering and disaggregation, causes rocks to crumble. Water, in either liquid or solid form, is often a key agent of mechanical weathering. For instance, liquid water can seep into cracks and crevices in rock.
