Answer:
12.25
sq m
Step-by-step explanation:
if circumference is 7 then the diameter is 7
Area = r²
A = (3.5)²
A = 12.25
Answer:
5700
Step-by-step explanation:
step 1 Address the formula, input parameters & values.
Input parameters & values:
The number series 2, 4, 6, 8, 10, 12, . . . . , 150.
The first term a = 2
The common difference d = 2
Total number of terms n = 75
step 2 apply the input parameter values in the AP formula
Sum = n/2 x (a + Tn)
= 75/2 x (2 + 150)
= (75 x 152)/ 2
= 11400/2
2 + 4 + 6 + 8 + 10 + 12 + . . . . + 150 = 5700
Therefore, 5700 is the sum of first 75 even numbers.
She is correct because a negative subtracted by a negative is positive.
