Answer:
11. 3,396
Step-by-step explanation:
Given:
Circumference of Mars = 10,664 km
Determine the diameter of Mars.
D = 2r
C=2πr
Solution:
Since we do not have the value of r, we will solve for r in terms of C.
C=2πr
10,644 = 2πr
r = 10644/ 2π
r = 1694.04 km
Now that we know the value of r, we can solve for d.
D = 2r
D = 2( 1694.04km)
D = 3,388.09 km
The nearest value is 3,396 km on the choices, but the answer rounded to the nearest km is 3,388 km
Answer:
225°
Step-by-step explanation:
π radians is 180°, so ...
(5/4)·(π radians) = (5/4)·(180°) = 225°

Answer:
3x + 2x
Step-by-step explanation:
Pretty sure its the first one because its the only thing that could come next.
"Around the garden"= circumference
Find diameter from circumference formula
Circumference= πd
19= (3.14)d
divide both sides by 3.14
6.04788= d
Find radius
d÷2= 3.0239
Insert r= 3.0239 into Area formula
Area= πr^2
A= π(3.0239)^2
A= (3.14)(3.0239)^2
A= 28.71 square feet
ANSWER: 28.71 square feet is the area of the new garden
Hope this helps! :)
