(b)(b)=25 cm2
b2=25 cm2
√(b2)=√(25 cm2)
b= 5 cm
Please note the square root of 25 was taken, as well as the square root of cm2.
Perimeter=4b
Perimeter=4(5 cm)
Perimeter=20 cm
Step:
A circle of radius = 12.5 or diameter = 25 or circumference = 78.54 cm has an area of: 4.909 × 10-8 square kilometers (km²) 0.04909 square meters (m²)
Answer:
A) v = T/2 - 5
Step-by-step explanation:
T = 10+2v
2v = T-10
v = (T-10)/2 = T/2-5
<span>2/3 + y - 4/5 = 1/3
y = 1/3 - 2/3 + 4/5
y = -1/3 + 4/5
y =-5/15 + 12/15
y = 7/15</span>
The answer is a I hope this helps your welcome
