A large pizza has diameter 36 cm and a medium pizza has diameter 30 cm. What is the difference in area of the pizzas? Round your
vladimir1956 [14]

Answer:

311 cm^{2}

Step-by-step explanation:

Taking a pizza to be a circle

Area of big pizza be x abd are of small pizza be y

hence difference = x-y

Area of a circle = \pi r^{2} where r is the radius

taking \pi to be 3.14

hence area x = 3.14 (\frac{36}{2} *\frac{36}{2}) = 1017.36

Area y = 3.14 (\frac{30}{2} * \frac{30}{2} )= 706.5

x-y = 1017.36- 706.5 =310.86 cm^{2}

310.86 cm^{2}

2.5 What is the difference between relational understanding and instrumental​
Afina-wow [57]

Answer:

Instrumental understanding – having a mathematical rule and being able to apply and manipulate it. Relational understanding – having a mathematical rule, knowing how to use it AND knowing why it works.

Step-by-step explanation:

Instrumental understanding involves “memorising which problems a method works for and which not, and also learning a different method for each new class of problems” (Skemp 1987, p. 159), is a desire to know “some kind of rule for getting the answer” (p. 155) so that a student can “latch on it and ignore the rest”
