She started with 60 pennies
<h3>Ratios and propotions</h3>
Let the number of a bunch of pennies she has to be "x"
If she gives 1/3 of her pennies to her older brother, she will have 2/3 x remaining
If she gives 2/5 of her remaining pennies to her younger sister, she will have 2/3x- (2/5 of 2/3x) = x remainijg
If Sally has 24 pennies remaining, then;
2/3x - 4/15x = 24
10x-4x/15 = 24
6x/15 = 24
6x = 15 * 24
x = 60
This means that she started with 60 pennies

Answer:
V= 125.6
Step-by-step explanation:
The equation is V=Bh
Since there is a circle you would substitute B for (3.14 x r^2)
V= (3.14 x r^2)(h)
= (3.14 x 4 )(10)
=12.56 X 10
V =125.6
