Answer:

646.04 cm³

Step-by-step explanation:

Cube volume formula:

V=l*w*h

V=8*8*8

V=512

Hemisphere volume formula:

V=(4/3πr³)1/2

V=(4/3π4³)1/2

V=128/3

Add both together

128/3 + 512 ≈ 646.04cm³

X^2 + y^2=40 and y=x-4 solve this simultaneous equation

inn [45]

Write x-4 instead of y.
x²+(x-4)²=40
x²+x²-8x+16=40
2x²-8x-24=0
x²-4x-12=0
(x-6)(x+2)=0
x=6 or x=-2

for x=6, y=6-4 = 2
for x=-2, y=-2-4 = -6

Which measure is cloest to the length of a side of a square that has an area of 221 square feet? 11.0 ft 14.69 ft 16.4 ft 55.2 f

Degger [83]

Answer:

14.69 ft.

Step-by-step explanation:

Area of a square:

A= $a^2$

Given:

A=221 $ft^{2}$

Solve:

221= $a^2$

$\sqrt{221}$ = $\sqrt{a}^2$

a is approx. equal to 14.87 ft.

which is 14.69 ft.
