Answer:
4. C
5. B
Step-by-step explanation:
4. Circumference = diameter * pi
pi is approximately 3.14
Diameter = 2*radius
Diameter = 2*8 = 16
Circumference = 3.14 (16), so the answer is C.
5. The question asking asking for the surface of the toy box.
Surface area of a cube = 6*the area of one face of the cube = 6 (edge * edge)
Substitute the edge with 2
Surface area of the toy box = 6(2*2) = 6(4) = 24
Surface area is 24 feet squared, so the answer is B
Hope this helps :)
Have an awesome day!!
Answer:
a = 10
b = 6.633
Step-by-step explanation:
x²+ y²= 125.
In this equation, the value of x and y represent the coordinates of x and y respectively of point on which the circle passes.
<u>(a,5)</u>
x²+ y²= 125
a² + 5² = 125
a² + 25 = 125
a² = 125-25
a² = 100
a = √100 = 10
(9,b)
x²+ y²= 125
9² + b² = 125
b² 125 - 81
b² = 44
b = √44 = 6.633
