18/m - 3
Step-by-step explanation:
Answer:132.25π m²
Step-by-step explanation:The circumference of a circle is 23π
On the other hand, The circumference of a circle = 2×π×r ; where r is the radius. Then by equating the last two expressions we get: 23π = 2πr then r = 23/2 then the area = π × r² = (23/2)²×π = (132.25)×π
Answer: 2535
Step-by-step explanation:
use order of operations (parenthesis, exponents, multiplication/division, addition/subtraction)
first ill handle the two innermost parenthesis
(4 + 3(2 - 8))
(4 + 3(-6))
(4 - 18)
-14
now lets move on to the next parenthesis
( 3 - 5^2(-14))
(3 - 25( - 14)
( 3 + 350)
353
now onto the last part of the problem
8^2 + 7 (353)
64 + 2471
2535 :))

Step-by-step explanation:
Answer:
HG and HI are 11(√3)/3 and 22(√3)/3 respectively
Step-by-step explanation:
Since triangle HGI is a 30-60-90 triangle, we can easily find HG and HI. HG is 11/(√3) because the longer leg of a 30-60-90 triangle is (√3) times the shorter base. 11/(√3) can be simplified into 11(√3)/3. Since HG is 11/(√3), HI is is 22/(√3) because the hypotenuse is 2 times the shorter leg. 22/(√3) can be simplified into 22(√3)/3. So HG and HI are 11(√3)/3 and 22(√3)/3 respectively.
