Answer:
72.96
Step-by-step explanation:
Let the first circle's radius be r and quarter circle's radius be R
Area of circle = π
= 3.14 × 8 × 8
= 200.96
Area of quarter circle = π/4
= 3.14 × 16 × 16
= 803. 84/4
=200.96
Area of shaded portion = (Area of Quarter circle - Area of semi-circle ACD - Area of triangle ABC) + (Area of the circle - Area of semi-circle ACD - Area of triangle ABC)
Area of Semi-circle = Area of the circle divided by 2
= 100.48
Area of triangle =
=
= 64
Therefore, The area of shaded portion= (200.96-100.48-64) + (200.96 - 100.48 - 64)
= 36.48 +36.48
=72.96
Answer:
Rate of Change: 2
Step-by-step explanation:
Rate of change is the same as slope:
( y1 - y2 ) / ( x1 - x2 )
( 2 - 4 ) / ( 0 - 1 )
( -2 ) / ( -1 )
2

Answer:
Part a)
Part b) Added only one side triangular face instead of three side triangular faces
Step-by-step explanation:
we know that
The surface area of a triangular prism is equal to two times the area of the base plus the area of its three triangular faces
so
Riley's error was
added only one side triangular face instead of three side triangular faces
