Answer:
75.36
Step-by-step explanation:
c=2
r
c=2(3.14)12
It is the last one (x+3)2
Answer:
y = 11
x = 8.6
Step-by-step explanation:
The small triangle with 30,32,y looks like right triangle
so according to formula a^2 + b^2 = c^2
so 30^2 + y^2 = 32^2
900 + y^2 = 1024
y^2 = 124 => y = 11
The larger triangle also looks like a right triangle
so according to formula a^2 + b^2 = c^2
(30 + 10)^2 + 22^2 = (32 + x)^2
1600 + 44 = (32 + x)^2
so (x + 32)^2 = 1644
x + 32 = 40.55
x = 40.55 = 32 = 8.55 = 8.6
Answer:
Step-by-step explanation:
Given
Required
The size of 
of height 
First, we calculate the width using the following equivalent ratios
Express as fraction
Solve for x
Hence:
--- approximated
So, we have:
The size (diagonal) is then calculated using:
--- approximated
