Answer:
When a prism has its bases facing up and down, the lateral area is the area of the vertical faces.
(For a rectangular prism, any pair of opposite faces can be bases.)
The lateral area of a right prism can be calculated by multiplying the perimeter of the base by the height of the prism.
Answer:
Step-by-step explanation:
<u>Area of the larger circle:</u>
<u>The shaded area:</u>
- π(2r)² - πr² = 75
- 3πr² = 75
- πr² = 25
<u>Area of the larger circle:</u>
Do you still want it as a fraction or a decimal?
If you want it as a fraction:
54/100= 27/50
72/100=36/50=18/25
90/100=45/50
In decimals:
54/100=0.54
72/100=0.72
90/100=0.90
