Area of the square base = 5^2 = 25 cm^2
Area of one of the triangular side = 1/2 * 5 * 8 = 20 cm^2 and there are 4 sides
So the surface area of while pyramid = 4 * 20 + 25 = 105 cm^2
Volume of the cone = (1/3) pi r^2 h
= (1/3) pi * 5^2 * 8
= 209.44 ft^2
Answer:
B. 2 (Second Option)
Step-by-step explanation:
Four times: ⇒ 4
Number:⇒ y
4y+3=11
<em>Subtract by 3 both sides of equation.</em>
<em>4y+3-3=11-3</em>
<em>Simplify.</em>
<em>11-3=8</em>
<em>4y=8</em>
<em>Divide by 4 both sides of equation.</em>
<em>4y/4=8/4</em>
<em>SImplify, to find the answer.</em>
<em>8/4=2</em>
<em>y=2 is the correct answer.</em>
<em>2 is the correct answer.</em>
Answer:
x x=-4 y=x+2
Step-by-step explanation:
Answer:
- 3
Step-by-step explanation:
Using the law of logarithms
x = n ⇔ x = 
let
(
) = n
(
) = n, then
= 
Since bases are the same on both sides then equate the exponents
⇒ n = - 3 → (4)
6.43 rounded to the nearest tenth is 6.40
The place after the decimal is the tenths place. We rely on the value of the hundredths place to know whether we round it up or we round it down to the nearest tenths. If the number is 5 and above, we round it up. If the number is below 5, we round it down.
3 is below 5 therefore from 6.43 we round it down to 6.40
