Find the volume of the composite figure to the nearest tenth.
use 3.14 for n

The volume of the rectangular prism is 8*6*3 = 144 cm^3
The volume of the cylinder is 3.14*2^2*5= 62.8 cm^3

144 + 62.8 = 206.8 cm^3.

The answer is D).

Answer: d. 39 cmin the diagram, the approximate length of the minor arc de is 39 centimetres.step-by-step explanation: the formula for the length of an arc in a circle is as displayed below.let the length of the minor arc de = xx = 2( pi )r × angle of sector / 360°from this, we will substitute the values given from the problem into the formula to obtain the length of the minor arc de.x = 2( pi )r × angle of sector / 360°r = radius = 25cmpi as an approximate value = 3.14angle of sector = 120°x = 2( 3.14 )( 25 ) × 120° / 360°x = 157 × 1 / 4x = 39.25x = 39 ( rounded to the nearest whole number as an approximate value )
