Answer:
The area of the base is = 5.2 cm²
Step-by-step explanation:
<em>First, we need to know the formula to calculate volume:</em>

<em>if we change to our equations to the values we know:</em>

<em>Since 3.14 is multiplying B,we can pass it to divide the volume to the left side:</em>

<em>We calculate the operation=</em>

<em>And the answer is 5.2 cm²</em>
<em>Let me know if you have any question :D</em>

Answer:
-84
Step-by-step explanation:
The formula for the nth term of a geometric progression is
Un = ar^n- 1
The sum of the first six terms of a geometric series (U6) = 21/16
Common ratio = -1/2 ,
a = First term ??
21/16 = a × (-1/2 )^6- 1
21/16 = a ×(-2^-1)^5
21/16 = a × -2^-6
Cross Multiply
16 × a × -2^-6 = 21
a = 21/16 × -2^-6
a = 21/16 ×- 1/2⁶
a = 21/16 × -1/64
a = 21 ÷(-1/4)
a = 21 × -4
a = -84
The first term = 84
Answer:
10
Step-by-step explanation:
Assuming that each square is one unit, you plug it into the distance formula.
The answer to your question is 8*5*4.
8*5=40
40*4=160 8 is twice of 4. the length is twice the width.
