1 answer:
The total surface area of the solid is 4651 sq cm
Step-by-step explanation:
Given,
The diameter of the base = 16 cm
Length of the cylindrical part (h) = 75 cm
The height of the solid = 90 cm
So, the radius of the base(r) = cm = 8 cm
The height of the cone = 90 - 75 cm = 15 cm
The slanting height(l) of the cone = cm = 17 cm [ by Pythagoras theorem]
To find the total surface area of the solid
The solid consists of two separate solids that are a cylinder and a cone.
So, total surface area (TSA) of the solid = TSA of cylinder + TSA of cone
To find the TSA pf cylinder
Formula
TSA of cylinder = 2πrh +2πr
=2πr(r+h)
=2 ××8×(8+75) sq cm
= 4173.7 sq cm (approx)
Again,
To find the TSA pf cone
Formula
TSA of cone = πrl +2πr
=πr(l+2) sq cm
= ×8×(17+2) sq cm
= 477.7 sq cm (approx)
Hence, total surface area (TSA) of the solid = 4173.7 sq cm + 477.7 sq cm
= 4651.4 sq cm

Answer:
The last graph
Step-by-step explanation:
We transform functions in the following ways:
- multiplying the function by a number to stretch or shrink it
- multiplying by a negative to flip the orientation of the function
- adding/subtracting a value to the input x to shift it horizontally
- adding/subtracting a value to the output (or outside the function operation) to shift it vertically or horizontally.
Looking at the equation we can see
- Vertically shrunk by 0.5
- Negative leading coefficient to flip the graph's orientation
- Horizontal shift of the vertex of 3 units to the left from (0,-2) to (-3,-2)
- Vertical shift of the vertex of 2 units downward (-3,0) to (-3,-2)
The last graph has vertex (-3,-2) and satisfies the the equation.
