We start with subbing in 25 to r, then we cube 25, which is equal to 15625.
We multiply 4/3 and pi. And lastly we multiply what we got by 15625 and either round the answer or fphaving fixed your calculator.
Answer:
10 tomato plants and
15 rose plants
Step-by-step explanation:
Let t be the no. of tomato plants,
And r the no. of rose plants
t + r = 25
t + 2r = 40
t = 25 - r
25 - r + 2r = 40
r = 15
t = 25 - 15
t = 10
