Answer:
Option C
Step-by-step explanation:
Given that area of a circle = 452.16 sq metres
Hence radius = ![\sqrt{\frac{452.16}{3.1416} } =11.9969 m](https://tex.z-dn.net/?f=%5Csqrt%7B%5Cfrac%7B452.16%7D%7B3.1416%7D%20%7D%20%3D11.9969%20m)
After rounding off we get radius = 12metres
To find circumference
We know that circumference of a circle = 2pir
= ![2(3.1416)(11.99694)=75.3984 m](https://tex.z-dn.net/?f=2%283.1416%29%2811.99694%29%3D75.3984%20m)
Option C is right
Option D is right
Answer:
2
Step-by-step explanation:
Answer:
9. 40°
10. 50°
11. 270°
12. 310°
Step-by-step explanation:
m∠BPC = 40° because it is complementary to ∠APB, which is 50°.
Arc AB is 50° because it will be equal to the central angle, which is 50°.
Arc ADC is 270° because it will be equal to the central angle, which is 270°.
Arc ADB is 310° because it will be equal to the central angle, also 310°.
You mean
the linear equations, 5x-y+1=0,4x-y+1=0
the slopes are 5 and 4 respectively.
it is clear that slope of first equation is greater that is it has a steeper graph therefore it Will always be greater than the other for x > 1
the same can be done by calculus; differentiation.
note y=5x+1 is always greater than y=4x+1 for all x>1
The centimeters in 23.6 can equal 9 inches within those amount of centimeters. 23.6 divided by 2.5 equals 9.44, rounding it equals to 9.
