How much is the cookie and popcorn
0.8 inches
the volume (V) of a sphere is calculated using the formula
V = πr³
change the subject and express in terms of r
multiply both sides by 3
3V = 4πr³ ( divide both sides by 4π )
r³ = 3V / 4π ( take the cube root of both sides )
r = ∛( 3V /4π )
sphere A with V= 40
r = ∛ (120 / 12.56 ) = 2.122
sphere B with V = 10
r = ∛(30 / 12.56 ) = 1.337
sphere A - sphere B = 2.122 - 1.337 = 0.8 inches ( to nearest tenth )
Answer:
1. B nearly 70%
2. C nearly 9%
Step-by-step explanation:
1. There are 26 people which agree with the question and 61 people which disagree with the question. In total, 26+61=87 people.
So,
disagree with question 1.
2. There are 87 people in total and only 8 females agree with question, so
of females agree with the question 1.
(210+200+190+180+300+150+90+x)/8=200
(1320+x)/8=200 /*8
1320 +x=1600
X=1600-1320
X= 280
Option A will be the correct answer
