First the 2 bases have surface area pi*1.25^2*2
Then the side
2.5pi*4=10pi
total of 9.817+31.415
=41.232
This approximation could be further round down for this problem to 41.2
Which makes choice C the correct choice.
A prime number is one that's only factors are 1 and itself. So 2 would be a prime number, 11 also, and 19.
Answer:
16/24 and 12/18, in simplest form 2/3
Step-by-step explanation:
8 parts juice
fruit and crushed ice = 3 + 9 = 12
ratio of juice to fruit and crushed ice is 8:12 or 8/12
8/12 (2/2) = 16/24
8/12 (1.5/1.5) = 12/18
in simplest form
8/12 (1/4 / 1/4) = 2/3
Answer:
D. 100 cm^2
Step-by-step explanation:
i did this before so ik im right
Given:
Volume of the cone = π r² h/3
radius of the cone is half the radius of the cylinder ⇒ r/2
height of the cone is equal to the radius of the cylinder. ⇒ r
V = 3.14 * (r/2)² * r/3
V = 3.14 * r²/4 * r/3
V = 3.14r³ / 12
