8 a :) The formula V = 112(2r + h) gives the volume V of a solid consisting of a cone of height h and base radius r attached to a hemisphere of the same radius. a Change the subject of the formula to h. b Hence calculate the height of the cone, if the solid has a volume of 55 cm3 and the common radius is 2 cm.

i dont know it

hi there!

question 1 answer: p/q can be terminating when q = 5^m * 2^n

question 2 answer: -1 and -1

question 3 answer: -4

question 4 answer: 5/12

hope this : )

“ a line segment that has the endpoints on the circle and passes through the midpoint is called the diameter. the diameter is twice the size of the radius. a line segment that has its endpoints on the circular border but does not pass through the midpoint is called a chord. a circle is the same as 360 small circle up the number 0 . i hope this .
