Answer:
the answer will be option A
Step-by-step explanation:
for the volume of a cube , we know,
(side)^3
so, here (2r)^3
= 8r^3
and the volume of a sphere is 4/3πr^3
so for a hemisphere it will be half., then 2/3πr^3
adding these two....we get
8r^3 + 2/3πr^3
= r^3(2/3π+8)
Answer:
The simplest way to teach middle school math scale drawings is to use real pictures to relate to each other to explain the concept. For example, scaling a red ball of 1" to a ball of 2" and so on. This will show how the ball increases by size by adding 1" each time.

Step-by-step explanation:
The diagonals of a parallelogram bisect each other , then
CO = OA = b
DO = OB = a
(a)
CA = CO + OA = b + b = 2b
(b)
DC = DO + OC = a - b
(c)
CB = CO + OB = b + a = a + b
