The radius of the larger circle is 10 cm the radius of the smaller circle is 5 cm what is the approximate area of the shaded region

Answers

Answer 1
Answer:

Answer:

The larger circle area is 314 cm

The smaller circle area is 78.5 cm

Step-by-step explanation:

The formula for circles area is r^2×π

r is radius to the power or 2 then multiplied by 3.14

The big circle is 10 so 10 to the second power is 100

So 100×3.14=314

Therefore, the big circle's area is 314 cm

You do the same for the smaller circle

5 to the second power is 25

25×3.14=78.5

And for this reason the area of the smaller circle is 78.5 cm

Hope this was helpful!

42 less than the product of 28 and an unknown number is 154

Answers

42 less than (-42) the product of (multiply) 28 (28) and an unknown number (x) is (=) 154
28 times x-24=154
pemdas
multiplication
28 times x=28x
28x-42=154
add 42 to both sides
28x+42-42=154+42
28x=196
divide both sides by 28
x=7
the number is 7
28X-42=154
+42 +42
-----------------
28X = 196
------ -----
28 28
X = 7
