r=10
V = 4πx10³/3
=4000π/3
V= 1333.33π (in terms of pi)
or
V= 4188.79(Nearest Hundredth).
Answer: 1 3/4 × 1 1/2
Step-by-step explanation:
Since Harry needs 1 3/4 cups of flour for one batch of cookies, but he wants to make 1 1/2 batches, the equation that can be used to find how many cups of flour Harry will need will be:
= (1 3/4 / 1) × 1 1/2
= 1 3/4 × 1 1/2
Therefore, to make 1 1/2 batches, the cups of flour needed will be:
= 1 3/4 × 1 1/2
= 7/4 × 3/2
= 21/8
= 2 5/8 cups of flours.
Answer:
39 students in the drama club, 25 in the yearbook club.
Explanation:
X=number of students in the drama club
Y=number of students in the yearbook club
X+Y=64
X−14=y
Subtract the equations
X−X+Y+14=64−Y
Y+14=64−Y
Subtract 14, add Y
Y+Y+14−14=64−14−Y+Y
2Y=50
Divide by 2
Y=25
X+25=64
Subract 25
X=64−25
X=39
