Answer:
No
Step-by-step explanation:
70 * 8 = 560, not 490
Instead, 70 * 7 = 490
Length of circumference is 2πr
2 π r and r is equal to 2 cm
I.e 12.5 cm
Answer:
This would be non linear
Step-by-step explanation:
Because a linear is a straight line
this would not equal to a straight line so it is non linear

Answer:
= 8sqrt2
Step-by-step explanation:
Area of a trapezium is given by the formula;
1/2(a+b)h
;
Where a and b are the parallel sides and h is the perpendicular height.
a = 3 cm, b= 5 cm
To get; h, we use the Pythagoras theorem;
h² = 3² - 1²
h² = 8
h = √8
= √4√2
= 2√2
Thus;
Area = 1/2(3 +5) 2√2
= 1/2 ×8 × 2√2
<u> = 8√2 cm² or 8sqrt2 cm²</u>
This is a puzzling question, so my answer is not 100%, but:
