Answer:
1.8m²
Step-by-step explanation:
∅= 51× π/180 = 17π/60
area of sector= 1/2 × r²× ∅
= 1/2 × 2²× 17π/60
= 34π/60
= 1.78m²
The answer is C.
The expression is telling you to multiply the parenthesis times four. When you multply two numbers, 
, it means that you're considering 
"copies" of 
, or if you prefer, repeated times.
So, you have
<- this is twice as much as the parenthesis
<- this is three times as much as the parenthesis
<- this is four times as much as the parenthesis
Answer:
It is right
Step-by-step explanation:
Because the hypotenuse must be greater than all the legs, we have that 
is the hypotenuse. So, we want to determine if 
.
This means the triangle is indeed right!
Find the amount of interest
Interest amount = (176400 - 112000) dollars = 64400 dollarsAs per the formula of simple interest we know thatInterest = Principal * Rate of interest * Time Rate of Interest = (Principal * Time)/Interest amount = (112000 * 30)/64400 = 3360000/64400 = 52.17So the rate of interest on the loan for the period of 30 years was 52.17%
