Answer:
39.0625%
Step-by-step explanation:
The area of a 25 inc TV screen is 300in²
The area of a 40 inch TV screen is 768in²
Percentage of area of the smaller screen to larger screen is;
300/768 × 100 = 39.0625%
Function
Use "vertical line test"
searched it if you don't know
Answer:
75%
Step-by-step explanation:
I took the test.
Answer:
V=(πr^2 x h)/3
lets use π as 3.14 cause I dont know what pi u using
3.14 x 4^2 x 15 = 753.6/3 = 251.2
If you're using π as your pi, than just replace 3.14 by π on calculator
Hope that answers your question
Volume of a cylinder is formulated as: π·r²h
Surface area of a cylinder is formulated as: 2π·rh + 2π·r²
So, for a:
Volume = π·5²·12 = π·25·12 = 300π
Surface area = 2π·5·12 + 2π·5² = 120π + 50π = 170π
And it's essentially the same process for the other questions.
