Given:
The figure of two semicircles with diameters 6 cm and 5 cm.
To find:
The area of the combined figure.
Solution:
It is given that the diameters of the semicircles are 6 cm and 5 cm so their radii are 3 cm and 2.5 cm respectively.
Area of a semicircle is:
So, the combined area of two semicircles with radii 3 cm and 2.5 cm is:
Round the value to the nearest tenth (one decimal place.
Therefore, the area of given figure is 24.0 sq. cm.
Answer:
see explanation
Step-by-step explanation:
Given the 2 equations
2x + 3y = 10 → (1)
x + y = 7 → (2)
Multiplying (2) by - 3 and adding to (1) will eliminate y
- 3x - 3y = - 21 → (3)
Add (1) and (3) term by term to eliminate y, that is
- x = - 11 ( multiply both sides by - 1 )
x = 11
Substitute x = 11 into either of the 2 equations and evaluate for y
Substituting into (2)
11 + y = 7 ( subtract 11 from both sides )
y = - 4
Solution is (11, - 4 )

Answer:
123
Step-by-step explanation:
Formula
distance = sqrt( (y2 - y1)^2 + (x2 - x)^2 )
Givens
- y2 = 17
- y1 = -10
- x2 = - 117
- x1 = 3
Solution
distance = sqrt( (17 - -10)^2 + (-117 - 3)^2 )
distance = sqrt( ( 27^2) + (-120)^2 )
distance = sqrt( 729 + 14400)
distance = sqrt(15129)
distance = 123
distance = sqrt
