Answer:
The answer is<u> D.</u> h+3/j+6.
Step-by-step explanation:
Given:
The equation h + 3 = jk + 6k.
Now, to get the mathematical expression.
So, taking common on R.H.S we get:
Then, dividing both sides by we get:
Thus,
Therefore, the answer is D. h+3/j+6.
Answer:
254 cm² (to 3 s.f.)
Step-by-step explanation:
Area of shaded region
= area of large circle -area of smaller circle
Radius of large circle= 15cm
Radius of smaller circle= 12cm
Area of shaded region
= π(15²) -π(12²)
= 225π -144π
= 81π
= 81(3.14)
= 254.34
= 254 cm² (3 s.f.)
