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:
16 feet
Step-by-step explanation:
This ladder and building creates a right triangle with 34 as the hypotenuse and 30 as a side. the Pythagorean theorem says that a^2 + b^2 = c^2 so 900 + b^2 = 1156. b^2 = 256, square root both sides and you get b = 16
Answer:
1. Answer is 162 2. Answer is 159.2
Step-by-step explanation:
In the first one we calculate both triangles by using and multiply it by 2 since we have 2 triangles
then we calculate the rectangle
and then we put them all together and get the answer which is 162.
in the second one we calculate the trapezoid then rhombus, then we put them together and get our answer which is 159.2
