Answer:
56.52 units² or 18π units²
Step-by-step explanation:
The formula for the area of a sector is:
A = πr²(x/360°)
where r is the radius and x is the measure of the central angle
Let's substitute the given measures into this equation:
A = πr²(x/360°)
A = (3.14)(12²)(45/360)
Solve:
A = (3.14)(12²)(45/360)
A = (3.14)(144)(45/360)
A = (452.16)(45/360)
A = (452.16)(.125)
A = 56.52
Therefore, the area of the sector is 56.52 units² or 18π units²
Answer:349
Step-by-step explanation:
Answer:
answer: 189
Step-by-step explanation:
Formula to find triangles area is base x height ÷ 2 So... 7 x 10 = 70 70 ÷ 2 = 35 Now sense we have 4 identicle triangles we will just do 35 × 4 amd 35 × 4 = 140 now for the square its simply just base x height so 7 × 7 = 49 now we will add these up...140 + 49 = 189 so 189 is the area. Hope this helps!
Answer:
30.1%
Step-by-step explanation:
Find the percent that was US exports by dividing 6.2 by 20.6, then multiplying it by 100
(6.2/20.6) x 100
= approximately 30.1
So, approximately 30.1% of the trade was US exports
