Answer:
Step-by-step explanation:
a^2 + b^2 = c^2.
if you draw out the triangle, you can substitute numbers into an equation.
6^2 + b^2 = 8^2
36 + b^2 = 64
b^2 = 64 - 36
b^2 = 28
b = 
To do this, find the surface area of each two-dimensional shape.
The two triangles have a combined area of 24.
The two rectangles have a combined area of 70.
The center rectangle has an area of 42.
Add them together to get 136 as your surface area.
50% is equal to the so we can easily divide 9 by 2 to get your answer 4.50 there is no hundreths for it is a clean divide (4.5×2=9)
Answer:
523.3 cubic inches
Step-by-step explanation:
A basketball has a diameter of 10 in. Using = 3.14, what is the approximate volume of the basketball in cubic inches?
The shape of a basketball is spherical.
Hence:
The volume of a basketball = 4/3 × π × r³
From the question,
π = 3.14
r = radius = Diameter/2
r = 10 in/2 = 5 in
Hence:
The volume of the basketball
= 4/3 × 3.14 × 5³
= 1570 ÷ 3
= 523.33333333 cubic inches
Therefore, the approximate volume of the basketball = 523.3 cubic inches
