Answer:
The answer is D
Step-by-step explanation:
Pi is 3.14. Multiply that by 10, and you get 31.4. The rectangle pan is 70 inches. Hope this helps.
B.
area of pan:
πr²
π(10)²
100π
314.16 in²
area of rectangle:
length * width
10 * 7
70 in²
greater area of pan by rectangular pan:
314.16 in² - 70 in²
244.16 in²
carnation $2.50; rose $3.00
Let c = price of 1 carnation.
Let r = price of 1 rose.
3c + 5r = 22.5
3c + 2r = 13.50
Subtract the se3cond equation from the first equation.
3r = 9
r = 3
Now substitute r = 3 in the first equation and solve for c.
3c + 5(3) = 22.5
3c = 7.5
c = 2.5
Answer: carnation $2.50; rose $3.00
perimeter of rectangle = 2(l+b)
= 2 (9+5)
= 2 X 14
= 28 cm
is the perimeter of rectangle
