Surface area of a sphere=4pi(r^2)
Volume of a sphere=(4/3)pi(r^3)
You need to find the r value to calculate surface area, so I'll solve for that first.
(4/3)pi(r^3)=2254pi
(4/3)(r^3)=2254
r^3=1690.5
r=(1690.5)^(1/3), around 11.9126m
Substitute this in to find surface area
A=4pi(r^2)=4pi(11.9126)^2
=1783.2818 m^2

Theo drove 228 miles in 4 hours. Lex drove 186 miles in 3 hours. At those rates, could either man drive 112 miles in 2 hours? sh

BigorU [14]

Yes, both men could drive at the rate of 112 miles in 2 hours. This is because you need to find the unit rate. For Theo's unit rate it is 57 miles per hour while Lex could drive at 62 miles per hour. Finally, the last statement ask if they could drive at a unit rate of 56 miles per hour and yes both men can.

Given that the points (-1,6). (3,6), (3, 1), and (-1, 1) are vertices of a rectangle, how much shorter is the width than the len

Ksju [112]

Since the given coordinates are already in order,
then and two consecutive distances between the coordinates will give length and breadth,

Using distance formula,
$\sqrt{ {( - 1 - 3)}^{2} + {(6 - 6)}^{2} } \\ = \sqrt{ { (- 4)}^{2} } \\ = \sqrt{16 } \\ = 4$
(we'll not consider the negative value since distances can't be negative)

Applying this again on 2nd and 3rd coordinates,
$\sqrt{ {(3 - 3)}^{2} + {(6 - 1)}^{2} } \\ = \sqrt{ {5}^{2} } \\ = 5$
(we'll not consider the negative value since distances can't be negative)

Since length's always gotta be greater than bredth
therefore,
the difference will be 5-4= 1 units

Hence width is 1 unit shorter than length.

Note: Unit used is "unit/s"

Write an equation of the line that passes through (2, 2) and is parallel to the line y = 7x

zimovet [89]

Answer:

y = 7x - 12

Step-by-step explanation:

Parallel lines have same slope.

y = mx + b

m - > slope & b -> y-intercept

y = 7x

So, slope = 7 & (2 , 2)

y - y1 = m(x -x1)

y - 2 = 7(x - 2)

y - 2 = 7x - 14

y = 7x - 14 + 2

y = 7x - 12
