Answer:
602.88in²
Step-by-step explanation:
Formula for finding the volume of oblique triangle is expressed as
A = πr²h
Given
radius r = 4in
height h = 12in
Substitute
A = π*4²*12
A = 3.14*16*12
A = 3.14 * 192
A = 602.88in²
Hence the area of the cylinder is 602.88in²
Answer:
B
Step-by-step explanation:
no need to explain

Let, the first (smaller) number = x
Larger number = 8x
Then, 8x - x = 70
7x = 70
x = 70/7
x = 10
& 8(10) = 80
In short, Your Numbers would be, 10 & 80
Hope this helps!
This is how the first one would be done. sorry if it’s a little messy the answer is 9. but try using photomath for the rest. it gives you the answer and explains how to do it
Area of a circle with diameter 14.
That means the radius is r=7 and the area is of course πr²
Answer: 49π
