12 • 16 = 192
5 • 3.14 = 15.7 15.7/2= 7.85
192 + 7.85 = 199.85
The area of the objective is 199.85
Answer:
78.38
Step-by-step explanation:
sum of sequence Find the sum of 46 + 42 + 38 + ... + (-446) + (-450) is -25,250
<u>Step-by-step explanation:</u>
We need to find sum of sequence : 46 + 42 + 38 + ... + (-446) + (-450)
Given sequence is an AP with following parameters as :

So , Let's calculate how many terms are there as :
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
Sum of an AP is :
⇒ 
⇒ 
⇒ 
⇒ 
Therefore , sum of sequence Find the sum of 46 + 42 + 38 + ... + (-446) + (-450) is -25,250
I am pretty sure the answer is,
B
