Answer:
C
Step-by-step explanation:
They both have x as their common like term
Volume of the cone = 1/3 pi * 3^2 * 4 = 12pi
Volume of the hemisphere = 4/3 pi 3^3 * 1/2 = 18pi
So the volume of the toy = 12pi + 18pi = 30pi = 94.25 cm^3 to nearest hundredth Answer
Surface area of hemisphere = 1/2 * 4 pi 3^2 = 18pi
Lateral Surface area of the cone = pi r l where l = slant height of the cone
Now l= sqrt ( 4^2 + 3^2) = sqrt25 = 5
So lateral S A = 3 * 5 * pi = 15pi
Surface area of the toy = 18pi + 15pi = 33pi = 103.67 cm^2 ( nearest hundredth) Answer
Answer:
Y = -35
Step-by-step explanation:
Y = 7x
x = -5
Since we know what X equals, we can plug it in for X in the top equation. Then, we can solve for Y.
Y = 7 • -5
Y = -35
7/3 does not equal 7/2
