Step-by-step explanation: So ig this wat you ASKED FOR?
The answer is C, because 10.5(10 1/2) x 7.5 (7 1/2) x 2.5 (2 1/2)= 196.875= 196 7/8
Answer:
for circle in circle: 75π
circle in square: 64-16π
note that answers are in exact form, since I don't know how the answer should be written (exact or decimal etc.)
Step-by-step explanation:
for circle in circle, we see that smaller circle (white circle) has radius 5 and big circle has radius 10. therefore we can find area of shaded area by doing
area of big - area of small
10²π - 5²π = 100π - 25π = 75π
circle in square, applying the same method, we can do square-circle
since the circle is inscribed in the square, the circle's diameter is 8, so its radius is 4
8²-4²π = 64-16π
The bank which will charge a customer more in fees if she writes 18 checks per month, and by how much is Bank A by $0.30
<h3>How to write and solve equation?</h3>
let
Bank A = 2.50 + 0.15x
= 2.50 + 0.15(18)
= 2.50 + 2.7
= $5.20
Bank B = 4 + 0.05x
= 4 + 0.05(18)
= 4 + 0.9
= $4.9
Difference in charges = $5.20 - $4.90
= $0.30
