Answer:
6,861 cm³
Step-by-step explanation:
First, find the volume of of the cylinder, the formula fr a cylinder is π·r²·h
π·9²·15≈3,817
Then, find the volume of the cone, 1/3(πr²)(h)
π·9²·12≈3,054
Finally, add them together to get ≈6,861 cm³
The expression -7y is a
term variable for : y
yes she can
y = 1.4(t) + 3
y = 1.4(15) + 3
y = 21 + 3
y = 24
since the total is 24, which is less than 25, she can talk for 15 minutes.
