Answer:

disagree

Step-by-step explanation:

If the triangle is right, then the square of the longest side must equal the sum of the squares on the other 2 sides.

longest side = 12 ⇒ 12² = 144

7² + 7² = 49 + 49 = 98

Since 144 ≠ 98 then triangle is not right

A large pizza has diameter 36 cm and a medium pizza has diameter 30 cm. What is the difference in area of the pizzas? Round your
vladimir1956 [14]

Answer:

311 cm^{2}

Step-by-step explanation:

Taking a pizza to be a circle

Area of big pizza be x abd are of small pizza be y

hence difference = x-y

Area of a circle = \pi r^{2} where r is the radius

taking \pi to be 3.14

hence area x = 3.14 (\frac{36}{2} *\frac{36}{2}) = 1017.36

Area y = 3.14 (\frac{30}{2} * \frac{30}{2} )= 706.5

x-y = 1017.36- 706.5 =310.86 cm^{2}

310.86 cm^{2}

Which equation can be used to find the volume of this solid?
Zina [86]

Answer:

V = StartFraction 7 times 6 over 2 EndFraction times 8

Step-by-step explanation:

Volume of a triangular prism is expressed as V = Base area × Height

Base area = area of the triangle = 1/2 × base × height

If the triangular base has a base of 7 inches and height of 6 inches.

The height of the prism is 8 inches.

Base area = 1/2 × 7 × 6

Base area = (7×6)/2

Height = 8

V = (7×6)/2 × 8

The right option is V = StartFraction 7 times 6 over 2 EndFraction times 8
