Answer:
351.68 cm^2
Step-by-step explanation:
We need to find the area of the frame itself. the radius of the inner circle is 12, but the frame has a radius of 4. You add 12 and 4 and you get 16. The formula for area of a circle is A=πr^2. So A= 3.14 x16^2. Then you have A= 3.14x 256 and you get 803.84. But we only want the area of the frame, so you have to get the area of the inner circle and subtract. You get A= 3.14 x 12^2. 3.14x144 is 452.16. 803.84-452.16 is 351.68. Hope this helped. :)
Answer:
351.86cm²
Step-by-step explanation:
12+4=16
(total radius of the whole circle)
use the formula a= πr² to find area
area of the full circle = π*16² (256 π)
256π - area of the smaller circle
256π - π*12²
256 π - 144 π = 112πcm² or 351.86cm² (to 2dp)
Hope this helps!!
A sailboat and catamaran are in a race to see who can sail across the Atlantic ocean the fastest..
.The sailboat covers a distance of 3240 miles in 8 days
.The catamaran covered a distance of 4020 miles in 10 days
If the sailboat is able to maintain a constant rate for 10 days, how many more miles would they have traveled than the catamaran?
Answer:
The sailboat would cover 30 more miles than the catamaran.
Step-by-step explanation:
To find how many miles the sailboat goes in 1 day (unit rate) you divide 3240/8 that gives you 405 miles in one day. Multiply that by 2 to get 810 miles in two days. Add 810+3240=4050. That shows that in 10 days the sailboat would travel 4,050 miles which is 30 miles more than the catamaran.

7x + 9 = 58 i need all the steps
Answer:
Step-by-step explanation:
7x + 9 = 58
-9 -9 Subtract 9 from both sides
7x = 49
/7 /7 Divide both sides by 7
x = 7 (this is an apporximation)
Answer:
7
Step-by-step explanation:
1st you need to subtract 9 from both sides like this: 7x+9-9=58-9. and you'll get 7x=49. Then, divide by 7 on both sides like this: 7x/7=49/7. and you'll get x=7.
