Answer:
- Circumference = 69.14cm
- Area = 380.29cm²
Step-by-step explanation:
Circumference.
Circumference of a circle is calculated by the formula:
= Pie * diameter
= π * diameter
= 22/7 * 22
= 69.14 cm
Area
Area of circle:
= Pie * radius ²
Radius = diameter/2
= 22/2
= 11 cm
Area = 22/7 * 11²
= 22/7 * 121
= 380.29 cm²
Answer:
Step-by-step explanation:
21.4÷4.75
- First- you have to move the decimal placement two times to the right
- Second- you have to put the number 21.4 under the dividing box
- Third- put the number 4.75 out to the left of the decimal box
- Fourth- when that's all completed you have to multiply the 475. until you get clos to the number 2140.
- Fifth- once done you have to subtract the multiplied number that you get you then subtract it from 2140
- Sixth- you keep on doing the fifth step until you get a reasonable answer
- Seventh- you write the answer down
- Eighth- there is no eighth step so you can stop reading this answer
