Brut [27]3 years ago
7 0

Step-by-step explanation:

The volume of a pyramid or cone is:

V = ⅓ Ah

where A is the area of the base and h is the height.

The pyramid has a square base, so:

A = s²

A = (7 cm)²

A = 49 cm²

The height is 14 cm, so the volume is:

V = ⅓ (49 cm²) (14 cm)

V = 686/3 cm³

V ≈ 228.67 cm³

A ball bearing is shaped like a sphere and has a diameter of 2.5 centimetres. What is the volume contained inside the ball beari
kvv77 [185]
To solve:

The diameter is already given (2.5), and it can be divided by 2 to find the radius.

2.5/2=1.25

Plug 1.25 and Pi into the equation for a sphere to find the volume:

(4/3)(1.25^3)(3.14)=8.177

Answer: About 8.18 cm^3

Lisa's new home had a purchase price of $185,500. She got a 15-year fixed mortgage for 75% of the purchase price. The interest r
Lady bird [3.3K]

Based on the purchase price of Lisa's home, the mortgage period, and the interest rate on the loan, Lisa's monthly payment is D)$957.72.

<h3>What is Lisa's monthly payment?</h3>

First find the loan amount:

= 75% x purchase price

= 0.75 x 185,500

= $139,125

Convert rate and period to monthly figures:

= 15 x 12                                                        = 2.990 / 12

= 180 months                                                = 0.24917%

Monthly rate is an annuity while the loan amount is the present value of an annuity:

Present value of annuity = Annuity x ( 1 - (1 + rate) ^ -number of periods) / rate

139,125 = A x  ( 1 - (1 + 0.24917%) ⁻¹⁸⁰) / 0.24917%

A = 139,125 ÷ ( ( 1 - (1 + 0.24917%) ⁻¹⁸⁰) / 0.24917%)

A= $957.72
