Answer: 117.226666667 cm^3
Step-by-step explanation:
So, we all know the formula for working out the volume of a cone is
V= 1/3πr^2h
V = 1÷3 x 3.14 × r^2 x h
The radius is half the diameter. Your diameter is 8 so the radius would be 4. And 7 is your height by the way.
So let's plot it all in!
V= 1÷3 x 3.14 × 4^2 x 7
V = 117.226666667cm^3
Round to the nearest 10 = 117.2cm^3
To the nearest 100 = 117.23cm^3
To the nearest whole number = 117cm^3
Answer:
107.20 euros.
Step-by-step explanation:
Let the amount she had initially be x euros.
Then we have the equation:
x - 0.40x - 0.35x = 26.80
x - 0.75x = 26.80
0.25x = 25.80
Multiply both sides by 4:-
x = 107.20 euros.
Answer:
125 barn 75 sleeping
Step-by-step explanation:
5/8 of 200 cows
of means multiply
5/8 x 200 = 1000/8 = 125
125 cows grazing
200-125 = rest of cows
75 = rest of cows sleeping
Answer: g(x) decreases by 7
Step-by-step explanation:
Simple algebra and substitution of variables for the number can help you to solve the problem,
g(7)=50-2(7)
g(7)=50-14
g(7)=36
I hope this helps
