The surface area of a sphere = 4πr²
4πr²=100π
Dividing both sides by 4π,
r² = 100π÷4π = 25
r² = 25
Taking the square root on both sides,
r = 5 centimeters
Step-by-step explanation:
12:15 I believe if you are saying rounding to the hour by 1/4 quarters
Step-by-step explanation:
Option D is the correct answer because we will cross multiply
4/6 = 9/x
4x = 54
X = 27/2
Answer:
60 m²
Step-by-step explanation:
Area of trapezium = 1/2 (a + b) h
= 1/2 (3 + 17) 6
= 1/2 * 20 * 6
= 60 m²
<span>2In4x= 2In8
ln(16x^2) = ln64
Multiply e by both sides.
16x^2 = 64
Divide both sides by 16
x^2 = 4
Take the square root of both sides.
x = 2</span>
