A = pi x r^2
48 = 3.141... x r^2
÷ by value of pi
15.278... = r^2
Square root the ans, to get r
Thus, R = 3.908..... So, radius is 3.9
2.
Circumference = pi x diameter
87. = 3.141... x d
÷ by value of pi
27.692............. = diameter
Radius is twice the diameter. So, divide diameter by 2 to find the radius.
27.692.....÷ 2 = 13.846...
Thus, radius is 13.8cm
Hope this helps!
Answer:
9 degrees
Step-by-step explanation:
given:
Initial temperature : 17 degrees
temperature change = reduction by 8 degrees (i.e - 8 degrees)
hence the final temperature
= initial temperature + temperature change
= 17 + (-8)
= 17 - 8
= 9 degrees
Answer:
The answer to your question is: side 3 = 2a + 6
Step-by-step explanation:
Data
Triangle
side 1 = 5a + 3 inches
side 2 = 2a + 3 inches
side 3 = ?
Perimeter = 9a + 12
Process
Perimeter = side 1 + side 2 + side 3
9a + 12 = (5a + 3) + (2a + 3) + side 3
side 3 = 9a + 12 - 5a - 3 - 2a - 3
side 3 = 2a + 6

Answer:
50 square units
Step-by-step explanation:
The outside square is 10 units on each side. If you fold the figure along each side of the shaded square, you find the white triangles exactly fill the shaded area. That means the shaded area is equal to the white area, so the shaded square is half the total area of 10×10 = 100 square units.
The shaded area is 50 square units.
