A. Length - 100 ft Width - 50 ft is the measurement of Tony's backyard.
Albert's Perimeter = 2(l+w) = 2(40+20) = 2(60) = 120 ft.
Tony's Perimeter = 120 ft * 2.5 = 300 ft
Tony's length = 40 ft * 2.5 = 100 ft
Tony's widht = 20 ft * 2.5 = 50 ft
To check tony's perimeter:
P = 2(l + w) = 2 (100 + 50) = 2 (150) = 300 ft.
r = 30 cm
formula: A = πr²
A = πr²
A = π30²
A = 900π
if π = 3.14, then the answer is 2,826 cm
if π is not defined, the answer is 2,827.43 cm
I think its 57.17 or about 52.2cubic inch
So total she saved 22+39 so far. That's 61 dollars in total (22+39=20+41=61).
She needs 100 dollars total, but she has 61 already, so she only needs 100-61=39 more: she needs 39 dollars more.
Answer:
b
Step-by-step explanation:
4.5% of 12000= 510
510x20= 10200
10200+12000
