What is the ratio for the surface areas of the cones shown below, given that
2 answers:
Answer:
16/9
Step-by-step explanation:
we know that R1/R2= 4/3 and L1/L2= 4/3. where R1 and L1 are cone dimensions 1 and R2 and L2 are cone dimensions 2.
We also know that the cone sourface is S=pi x R x L .
So that S1/S2= (pi R1 L1)/(pi R2 L2)
replacing and operating mathematically
S1/S2=R1 L1/R2 L2 = R1/R2 L1/L2=4/3 4/3= 16/9
Answer:
16:9
Step-by-step explanation:
If the linear ratio is 4:3, the area ratio will be the square of that.
(4/3)² = 16/9

Answer:
-5
Step-by-step explanation:
gradient = change in y ÷ change in x
gradient = -5 ÷ 1 = -5
Answer:
y = 1/25
Step-by-step explanation:
Reciprocal of y^(1/2) : 1/y^(1/2)
1/y^(1/2) = 5
y^(1/2) = 1/5
y = (1/5)^2
