Answer:

312 ft²

Step-by-step explanation:

3 rectangles

2 triangles

4 yd = 12 ft

A = 4ft×12ft + 8ft×12ft + 10ft×12ft + 2×6ft×8ft/2

= 48ft² + 96ft² + 120ft² + 48ft²

= 312 ft²

24 x 12 1/2 x 12 3/4 what is the volume of the fish tank

hjlf

Answer:

The volume is 3825 cubic units

Step-by-step explanation:

To find the volume of the fish tank multiply out the dimensions.

We were given the dimensions as:

$24 \times 12 \frac{1}{2} \times 12 \frac{3}{4}$

Change the numbers to improper fractions

$24 \times \frac{25}{2} \times \frac{51}{4}$

We cancel out to get

$3 \times 25 \times 51$

$3825$

The circumference of a pizza is 56.52 in. One-fourth of the pizza has been eaten the area of the remaining pizza in sq. Inches r

BabaBlast [244]

Circumference = πD
πD = 56.52
D = 17.99 in

Area of the pizza = π (17.99 ÷ 2)² = 254.19 in²

Area of the pizza eaten = 254.19 ÷ 4 = 63.55 in²

Area of the pizza remain = 254.19 - 63.55 = 190.64 in²

Answer: 190.64 in²

18. In the figure, o is the center of the circle passing through P, Q, R and S. If angle SOQ = 150°, find the values of x and y.

AveGali [126]

Answer:

x = 75°

y = 105°

Step-by-step explanation:

Angle subtended on the circumference of the circle is half of the angle subtended on the center of the circle.

$\therefore m\angle SRQ = \frac{1}{2} \times m\angle SOQ\\\\\therefore x = \frac{1}{2} \times 150\degree \\\\\red{\bold{\therefore x =75\degree}} \\$

Quadrilateral PQRS is a cyclic quadrilateral.

$\therefore m\angle R + m\angle P= 180\degree \\\\\therefore x + y = 180\degree \\\\\therefore 75\degree + y = 180\degree \\\\\therefore y = 180\degree - 75\degree \\\\\purple {\bold {\therefore y = 105\degree}} \\$
