Answer:

1st choice : 706.5 square inches

Step-by-step explanation:

circumference is pi times diameter

divide 94.2 by pi to get diameter = 29.9847912785

diameter 29.9847912785 divided by 2 is

14.9923956393 which is the radius

area is pi times radius times radius again

pi times 14.9923956393 times 14.9923956393 =

706.141834613

What is the volume of a square pyramid with base edges of 60 inches and a height of 10 inches?

vichka [17]

Answer:

The volume is $12000 in^3$

Step-by-step explanation:

From the question ,

$L= 60\:in.$ and $H=10\:in.$

The volume of a pyramid is given as

$V=\frac{1}{3} \times area\:of\:the\:base \times height$

From the question, the base of the pyramid is a square.

Hence base area is given by $L^{2}$

This implies that the volume of the pyramid is

$=\frac{1}{3} \times L^{2}\times H$

$=\frac{1}{3}\times 60^{2} \times 10$

$=\frac{36000}{3}$

$=12000 in^3$

zheka24 [161]

Answer:

FV= $4,948.16

Step-by-step explanation:

Giving the following information:

Number of periods (n)= 10

Interest rate (i)= 2.15% compound interest annually

Present value (PV)= 4,000

<u>To calculate the future value, we need to use the following formula:</u>

FV= PV*(1+i)^n

FV= 4,000*(1.0215^10)

FV= $4,948.16
